Even though I made very little progress to my map, I decided to mod yours first. Hmm, 4 mins map. Please excuse my language, don't take it personally my friend.
Feel free to ignore comments you don't like.
I would like to start with Floor 100 even though you wanted me to mod 1 and 10 XD.
[Floor 100]
00:00:454 (1,2,3) - I found it is very annoying to see this stack right from the first beat. Consider to spread it out.
00:01:795 (5,6) - From the end of the slider, the volume suddenly spikes up. Why can't it stay at 20% volume. It was an unexpected jump in volume for me.
00:03:135 (7) - 25% volume? or 30? 30% sounds fine to me.
00:05:985 (1) - Maybe I have a sensitive ear. I found it is way too loud. I feel the hitting beat covers the sound of the song.
00:06:990 (2) - Are you really want to do this?
00:32:633 (1,2,3,4,5,6,7,8) - I hated this kind of unexpected "fast hit"(? - - what is that called in English?) To me, this part is supposed to be nice and easy. Yeah, you heard the drums, but... I recommend to replace this with a single back-and-forth note. There is just not enough of "momentum" built up before this harsh chain note.
01:10:175 (2) - Again, this is just mean. XD
01:05:314 (8) - For my first play. I hit a late 50 here, because I did not expect this. Consider to delete this. Please. XD
01:16:208 (1,2,1,2,1,2) - It is not like I can't understand this increased jump pattern. I have no suggestion. I just want to let you know it bothers me when I played.
01:24:085 (6) - Inconsistent distance. Consider to play this on top to make a kite.
01:37:493 (4,5,1,2,3) - To me, the note density here is little too high. It is hard to see.
01:56:767 (5) - This note is not only mean but out of regular distance. It will be perfect if place it at the end of the slider.
Please refer to the previous comment to the second verse part. It seems the same isn't it.
02:51:404 (1,2,3,4) - ???? I know it is hard to map the solo bridge part of Jpop. My take is that I would just follow the guitar.
03:07:828 (1,2,3,1,2,3,1,2,3) - This quiet solo sing part is kinda weird, especially at here. Since it is the calm part, I suggest not to do any outrageous arrangements like this. From my experience, these calm parts give me the most trouble. Good luck.
03:23:582 (1,2,3,4,5) - The rhythm did not suggest this 1/8 5 circle set. Consider deleting 3,4,5. Use a slider at 3 which ends at 5.
03:33:973 (1,2,3) - Awkward note time. Maybe this sounds better
03:36:823 (4) - Delete, rhythm did not suggest this either.
03:43:862 (4) - ^
03:48:722 (1) - Consider switching 1 and 2
03:55:091 (3,4,5,6) - Oh wow, these are some fierce notes. I like variety, but I suggest you'd better be consistent with the space. I notice that not a lot of people like increase jumps.
Even with those distance and placing issue, I was more comfortable playing this than your previous Floor 10 like a month ago. Good job, I really like your sliders. I can't make pretty sliders like these lllorz.
Sorry, but I guess only one more difficulty. (This takes longer than I expected.) I will do Floor 10. Let's see how much has this improved. Huh, there is Floor 50. It is only 2:51 long.
[Floor 10]
00:13:862 (1,2) - I don't like the idea of stacking in Normal Difficulties.
00:14:197 (2) - Clap? I don't feel like it. Delete this.
00:35:649 (3) - I got a quicker 100 here. In fact, it is hard to read the rhythm out even for me.
00:38:666 (1) - Stacking. I will stop pointing out stacking.
00:43:359 (4) -
Unrankable It went out of bounds.
01:01:124 (1,2) - 16th note in normal, and it is stacked. I think this might be too hard for normal. Save these in harder difficulties.
01:03:471 (2) - out of bounds. This does not seem like a little bit out of the grid. Generally, I would avoid to go out of the grids.
01:05:314 (1,2) - Difficulty issue
01:07:325 (1,2) - ^
01:14:867 (1,2,3) - these are definitely too hard for normal
01:10:677 (1,2,3,4,5,6,1,2) - ^
01:16:208 (1,2,3,4,5) - ^
For those 1/16 notes, I this it wouldn't be too bad if you use them sparingly. Placing before a slider feels OK. However, placing at the end of slider, consecutive 2 sets are just too hard for normal. From 2:48 to 2:59, it looks great. Try to employ this kind of pattern for other places. Those aforementioned problems pretty much sums up my mod for this difficulty.
02:19:057 (1,2,3) - This is a pattern for hard difficulty
03:46:040 (1,2) - Consider to use a circle at 1. and a quick slider starting at the end of the "1" slider and end at 2.
03:53:750 (4,1,2,1) - Very hard to read. Spread it out a bit.
That's all I have for 2 hrs. Good luck. I will come back and see after a while. Floor 100 looks great!
