Hello, congratulations for get this mapset qualified but there are some things that concern me a lot and for obvious reasons could be improved.
DiFf_(k)NAMEBest of luck.
- 00:01:586 (1,1,1,1) - These kind of patterns look good and are awesome if they fit, but this is not the case here. In this song the music and the voice at the beginning sound consistent and there technically is no change in the music. I would like to recommend you to do something different instead. That's just wrong, the background sound is being increased in volume, the vocals become more intense, I am trying to understand why you would say something like that. I like that, it fits, it plays well, it looks well, so I can't really agree on that.
- 00:05:586 - 00:10:586 - The whole section is quite weird itself, due to that there are some beats that were completely ignored so it can be somehow difficult to understand and to play play also these changes of speeds doesn't helps at all neither. It's not complicated at all. Did you even try playing it? Lett me start with the SV changes: 00:08:586 (8) - Done to make the reverse arrow more visible, it has no impact on the gameplay, at all. 00:08:986 (1) - Returning to the original SV before this change. 00:09:586 (1) - Slight increase to make a transition into the next section, since 0.5 -> 1.5 is quite huge, reducing the gap helps. As for the section itself, I can't follow everything, it sounds awful, takes emphasization from vocals, too dense and more stuff, present rhythms are well thought and placed, if you had any suggestion for improvement, I'd like to hear that.
- 00:29:786 (1,2) - Could you explain to me why you've used a spacing lower at this section in compared to the rest that is technically the same kind of rhythm and that you've added jumps there? Valid concern. But, the patterns in this section use mostly the same rhythm and similar pattern structure, I am not using the same spacing all over this section, it makes it unnecessarily boring. Perhaps it looks a bit odd in the editor, but I can assure you that the whole section plays really well, this specific pattern does not stand out. I'll elaborate a bit more on the spacing anyway - it is quite similar to 00:28:186 (1,2,3) - in that manner, the pattern looks different, but it is spaced the same, giving emphasization to the last slider, if it's such a huge concern I might change it, but it doesn't really matter in my opinion.
- 00:10:586 (1,1) - The pitch in both sections feels almost the same. The only difference is the sound finish at the background but the voice seems like the same, so a change of speed in this part makes no sense at all. Please, try putting a bit more thought, it's clearly obvious for everyone. 00:10:586 (1) - The sound here is unexpected, giving it huge SV allows the momentum of the surprise to be actually played, at first I wanted to extend 00:10:386 (3) - just to follow the vocals, but it was awful, so I had to follow this note, even though it disturbs the vocals, hence the surprise. 00:10:786 (1) - There's nothing new on the sliderhead, some weird sound started playing but the intensity from the previous slider is gone, reducing the SV is just appropriate, but I ended up making this whole section gimmicky and fun, and it makes sense too.
- 00:32:786 (7,1,2) - I really don't understand the point of the constantly mapped into a double BPM and then go back to typical 1/2 rhythm? actually this could be even more confused due that the previous object is 1/4 and then swap it into 1/2 is difficult to read anyways I'm quite sure that most of the players will be confused or probably will fail that part so I would suggest you remap the whole pattern by anything else. It is done because the rhythm changes, unlike the previous patterns, there are no vocals at 00:32:986 (1) -, meaning I can't use the same pattern there, anyway there isn't any point of having 00:32:786 (7) - as a 1/4 slider because of the sudden shift to a single 1/2, it just plays odd, I did try it before and it did not work at all. No players got confused here, they aren't supposed to predict how the song plays, but read it and react accordingly, how are you so sure they will fail?
- 01:03:786 (1,2,3,1,2,3,4,5,6,1) - The same thing happens here, just that in this part it is a bit different - but I guess you get the idea. I don't, we are not in the kiai anymore this is an intersection between both kiai sections, mapping any 1/4 on those 01:03:786 (1,2,3) - is just wrong, nothing supports it, and it takes away the intensity and impact of the next stream.
- 00:40:386 (2) - This SV makes no sense, the vocal is not that much lower to do something like this. Yeah, this is gimmicky, might a bit hard to understand it immediately. I had explained this whole section before in some comment that I can't seem to find, so I'll just explain again. 00:37:786 (1) - till 00:47:386 (1) - is a section that can get cut to 3 sections, the first two are quite similar, vocal intensity is medium+- and it doesn't really change much, therefore they are mirroring each other, the thitd section is irrelevant in this explanation so I'll cut to the mentioned slider - because the sections are mirrored, the last and first notes of the first and second sections respectively are identical, I wanted to make something that allows the player to actually sense the cut between the sections, the slow reverse slider does it in a nice fashion, both time the head hits it's on a vocal and the slider doesn't put any pressure at all as he plays a mere transition into the upcoming section (I use this word a lot don't I)
- 00:43:286 - How about to add something clickable here? There are some sounds that are quite noticeable. It's not that noticeable in my opinion, but it does exist. I did follow this note on Insane but not here, my claim behind this is because I want the mirroring pattern to be kinda perfect, the triplet wouldn't work if a sliderend is a part of it, it's just odd. Yeah this might not be the best explanation, but I simply wish to undermap it.
- 00:51:186 (1,2,3,4,5) - Overall it's not that bad but I'm pretty sure that this could be more polished, try to make it consistent. I am lost on this one, what do you mean by making it more consistent? Spacing is increasing, creating a triangle that builds itself from inside, what's wrong here?
- 00:56:386 (1,2,5) - I think these kind of jumps are quite inconsistent because the background sound seems like the same all the time and having jumps like this is weird and obviously plays bad. Listen to the violin, I tried following the drums too but as the strongest drums land on the blue ticks it's quite hard, the violin supports this pattern really well, nothing I can add here. But I wonder, how did you conclude that it plays bad? I don't really like this judgement.
- 00:57:186 (7,1) - What are you trying to emphasize here? Last violin note, it's held and placing it this way makes the whole pattern consistent, along with some buildup to the upcoming vocals.
- 00:57:786 (3,4,5,6) - I really would like to see other kind of patterns here, apparently your intention to make it fun is great but the kind of flow you've used seems inappropiate and the cursormovement feels forced as well. Hm, it can be improved indeed, changed.
- 00:58:586 (1,2) - Same as above. That's actually just fine, a bit forceful yeah, but the drums supports it regardless, it's cool.
- 01:14:986 (1,2,3,4,5) - This is way too much for an extra difficulty, the amount of objects in a such a short time feels too dense in my opinion. Egh.. what? It's literally a 1/4 stream, the whole song is as dense as this.
First of all, I thank you both for your time you took to help and improve this set.Stjpa wrote:
actually I didn't want to mod but it seems like this map needs some. :v
[Easy]
• In the beginning I can't really figure out your system of how ur whistles are placed. It definitely can't be that one "whoosh" sound because it would make the hitsounding inconsistent except you wanted it to be lol. They were copied from the highest diff, but because it is not as dense as the other one the hitsounds are different, fixed it up a bit.
• 00:48:186 (2) - Why didn't you place this slider on the previous red tick for the vocals? You used 1/2 in the kiai too, so this would be a great transition if you ask me. I definitely agree, it's much better.
• 01:09:386 (3) - Shouldn't there be a clap on the sliderhead? Seems inconsistent otherwise. Claps are on redtick, so nope.
[Normal]
• 00:10:386 (5) - Not really satisfying that the downbeat which has a prominent sound on it is not clickable. It's fine, main focus is the vocals, and the halt after the downbeat creates a nice effect with the sliderend.
• 01:17:386 (1,1) - ^ and especially here you can't use an excuse because there's no reason at all to ignore it. There is, vocals. Same happens on advanced but you haven't said anything.
[Advanced]
• 00:24:186 (6) - A kickslider in an Advanced? It's already meh to use them in a Hard. It's pretty good with the violin, what's wrong?
• 00:35:786 (3,4,5) - Not really a problem, but why would you use a custom stack so randomly? It was stacked normally before, however someone suggested I do this to avoid overlapping with 00:35:186 (2) - because of the stack leniency.
Hard is fine, but I really don't know what to say about the spacing in Insane. For that difficulty it seems way too much sometimes.

Disrespectful? for posting their concerns about your map during Qualified period? qualified period is supposed to be the time where your map get criticism from the community, the one being disrespectful is you, by discouraging people from checking qualify maps, is true that Hula was a bit rude, but take a more deep look to Gero mod, I think you can still improve your map with it.Avishay wrote:

My opinion differs from yours, as long as this is not a traditional map, you still may interpret it in a bad way, even if you are experienced.Natsu wrote:

I really didn't want to post in this map thread because I feel like the highest diff's basic concept is sound but could do with large swaths of remapping entirely to pin down the concept (right now with everyone pointing out minor flaws and errors you end up with a patchwerk mess, better to remap with so many bandaids being forced onto it)
but
what the f***is that supposed to mean?
I thought qualification was supposed to be about QAT checking to make sure maps are error free in the sense that anything clearly looked over (missing hitsounds, wrong snaps, unrankability, etc)
not about having "the community" (which almost always consists of the same handful of people) point out personal judgements on a person's mapping style.
This is just an example, but if you, a modder, were to say "These kind of patterns look good and are awesome if they fit, but this is not the case here. In this song the music and the voice at the beginning sound consistent and there technically is no change in the music. I would like to recommend you to do something different instead." and the mapper were to respond "the volume itself is increasing and thus the spacing and slider speeds are" then that's all that's necessary.
I'm tired of people throwing pointless walls of text to make their posts look big and scary during qualification. It's underhanded and disgusting. Stick to any actual, valid concerns about the rankability of certain patterns. If you think the flow is shit, if you don't like how it plays, go somewhere else. There are hundreds of other maps in pending that could do with that sort of modding. Keep it out of qualification. If it's good enough for a handful of other BNs, then it's good enough for ranking - whether you personally like it or not.

- [diff_name]
- 00:01:586- volume of this slider sounds a bit loud imo, reducing to 30% looks better
- 00:02:586 (1,2) - hmmm, this high spacing between sliders with low sv at the beginning of the map plays kinda uncomfortable (at least for me exactly). At least 7x between sliders could works better I admit it's a bit extreme but I'll keep it anyway, it's fun and not hard at all.
- 00:04:186 (1,2) - something similar, but 8x here could works good. Anyway you should get more opinions about it I will.
- 00:10:586 (1,1,1) - since you had mapped these sliders to vocal, would be good you will make muting of the tails of these sliders, cuz they haven't some sounds
- 00:14:686 (7) - this combo feels a bit long, so I recommend you add nc here since spacing was changed
- 00:19:586 (6) - nc would be good too for better readability of stack
- 00:22:986 (7,1) - just you could improve this blanket
- 00:23:386 (1,3) - seems you made these 1/2 sliders intentionally, but anyway I think that mapping of 1/4 would work good cuz fit with song better. just replace these sliders to 1/4 repeats looks like great idea, just try. https://osu.ppy.sh/ss/5235431 I don't really like those, not a fan of such patterns.
- 00:25:986 (5) - I'd add nc's for all these sliders cuz sections with 3 kicksliders looks different from previous patterns Yeah but it's consistent, NC would just be too spammy.
- 00:49:186 (1,1,1,1,1,1,1,1) - nc spam looks fine for me, but you could make the placement of notes more structured, now they looks kinda randomly and doesn't so understandable imo I tried make it something that supports back&forth movement, it seems good for me.
- 00:51:186 (1,2,3,1,2) - seems whistles fit good with these circles, cuz we have only vocal without music, just try again
- 01:15:986 (2,3,4) - ^same for heads of sliders
- pretty good stuff, and remapped diff seems better for me than before lul

[name diff]
00:02:586 (1,2,4,1,2) - this spacing is really overdone here, this is so calm, it doesn't matter if there is a buildup sound, it just doesn't call for this spacing, you should try emphasizing differently here I'll keep that in mind.
00:05:586 (4) - then it's weird you put no pressure here when you focused so much on spacing the vocals uhhh
00:07:386 (4) - dunno if you just don't nc here cause it looks better, but it breaks consistency
00:08:786 (2) - might sounds dumb but, I'm assuming you nced 00:08:586 (1) - because of sv change but didn't nc 00:08:786 (2) - tbh I find no need to nc 00:08:586 (1) - in the first place if you don't follow your ncing logic,
00:09:586 - aaa this green line does nothing, I guess it won't hurt to remove it
00:19:586 (6) - nc for consistency
00:28:486 (2) - you can possibly polish this slider, I just find it ew atm, 00:29:786 (1) - is much better
00:35:386 (1) - ctrl g plays much better since you made it linear it's kick slider and has even amount of space between 00:34:986 (3,4,1) - on the clickable object, it will not feel comfy when dealing with same movement on different distance
00:39:786 (6) - I disagree with changing the shape here, if you keep it like 00:38:186 (3) - 00:38:986 (3) - it will be much cooler imo Feels forced for me
00:39:386 (4) - also nc
00:40:498 - slider end unsnapped
00:58:986 (2,3) - looks sloppy, I'm sure you can polish
01:03:186 (7) - nc?
01:11:186 (7) - nc instead of 01:11:586 (1) - ? seems more reasonable to me if you compare note intensity, also I dunno if it's good here to keep that slider on downbeat even if you follow that vocal, the instrument is also strong here
01:13:186 (8) - missing clap on sliderhead
01:12:786 (7) - I'd suggest nc here, remove nc at 01:13:986 (1) - and add nc 01:14:586 (3) - or 01:14:186 (2) - ,the slider end would be ideal place for nc but you have it on slider end which I don't agree either xd, then nc 01:14:986 (5) - because of sv change at 01:15:386 (9) - and just fits the music, then removing nc on 01:15:786 (1) - and adding on 01:15:986 (2) - would make more sense to the music atleast
01:16:988 - slider end unsnapped
ai mod pointing the stack leniency thing, dunno up to you to change it or not
oh and 00:16:786 (5,1) - 00:24:086 (1,2,3) - 00:17:486 (3,4,5,6) - not sure if you intended to keep the antiflow movements here, but they are only for challenge if anything since they don't really play that well, unless you're beyong this level
didn't expect to write much here, overall the aesthetics were the main thing for me, but that's subjective I guess. I liked the kiai tho xd
hope it helps somehow, good luck requalifying

map: https://osu.ppy.sh/s/455756 just pick one of the two extras or something, it doesnt have enough mods to go for ranking yet anyways :v
general stuff was already checked well enough here in the past so I'll skip that
[ex ex]
00:05:586 (4) - having this spaced like 00:03:986 (4) - (or even more) would fit the vocal+pitch wy better than a stack
00:09:786 (3,1) - not stacking this would make 00:12:986 (5,1) - easier to get since right now it'S easy to expect the second one to also be a stacked 1/1 (at least is messed me up on my sightread and I'd consider my ar9.3 reading fine enough)
00:17:286 (2) - would work wel las a kickslider to cover the weaker sound on the white tick, probably sth like http://i.imgur.com/uKrdTOy.jpg
00:24:286 (3) - slider starting on blue tick doesnt work that well here cause cause what? .-, blame the song
00:29:786 (1,2) - i hate pointing out minor visual things, but http://i.imgur.com/02NX78U.jpgwould look so much nicer than the sligh overlap on the slidertail
00:40:386 (2) - is unsnapped, you probably wanted 0.9x sv here?
00:46:586 (2,3) - if you go with the "muted 1/4 sliders to emphasize vocals" thing then shoudnt those also be such sliders?
or maybe at least 00:45:786 (5,2) - cause they even have weak sounds on the blue ticks
01:03:186 (7) - missed nc? fits your 4/1 pattern in the chorus
01:16:786 (4) - unsnapped again, should use 2x sv or change the length slightly, but the first option fits the pattern better
01:17:786 (1) - could be spaced more to emphasize the finish, with how high the spacing before is it's unlikely to be misread as 1/2, sth like http://i.imgur.com/xOLAn9S.jpg
01:18:386 (4,6) - would work well with a bit higher sv cause they are pretty strong and high pitched

00:43:986 (3,4,5) - how about using same pattern with 00:43:586 (1,2) - . now I think it's not suitable for downbeat. It's fine because of the vocals.
00:56:386 (2,4) - blanket
00:52:186 (1) - How about using NC every 2 downbeat? it's kiai part.
01:06:786 (7) - NC
01:17:386 (1) - I think using more fast slider would be better..but it's your interpretation It is.
00:58:986 (2,3,4) - DS between 2,3 is too low, considering other same patterns and song's difficulty. And one more, it's too linear pattern (2->3->4) I felt a bit hard to hit 4. How about at least use different flow like here 01:11:986 (4,5,6) - ? It's not completely linear, I agree it's a bit tough to play, but it is planned in a way that allows you to quickly move to 3 without actually following 2, I think it's cool.
Good luck! I like this map.

I also think that the previous one was better, maybe mix the new and previous one together? Or just maybe this mapset doesn't need an Extra, that would also be an option, well making insane a bit harder then.
Looking forward to this map evolution!
I would do a proper mod, but my experience isn't that high so idk.
