Genocide again. I've played this map quite a bit now, so I'm going to give mostly opinion based change advice. The ones in Red are global changes that I think everyone would agree on, not just me.
00:12:554 (1) - The countdown needs to go. Not only do maps not really use it more, but the high BPM makes it seem like the countdown doesn't go with anything.
00:39:366 (3) - This big downbeat here seems lost since it is within a combo and does not start a new section.
00:41:366 (3) - Same thing as above here.
00:43:366 (3) - And here as well. After playing this map a lot I noticed that it lacked "kick", for a lack of a better term. The map overall didn't feel SATISFYING when you hit the big beats, and I couldn't understand why until now. You're not accenting big downbeats in the song.
There are MANY occasions where this is the case, so I'm going to stop pointing them out, I can point them out in another post if you need me to.
00:38:366 (1,1,1) - Not sure why these have their own combo color, just because they are somewhat stacked? I'm probably in the wrong here for saying they should be all one combo, though.
00:48:991 (1,2,3,4,5,6,7) - These double taps kind of come out of nowhere and are, to me, annoying to play. It kind of messes with the flow since the rest of the map before it has been constant cursor motion and there's nothing really in the music to suggest double-tapping.
00:51:866 (1,2,1,2,1,2) - These should probably be all one combo, but again I could not know something about this.
00:58:116 (1) - You lose an important beat in this slider, feels weird not to hit it.
01:05:991 (1) - This spinner REALLY messes with the flow. Again, it doesn't feel satisfying to spin past a cool part in the song and it kind of comes out of nowhere.
01:09:366 (1) - Still don't know why you're not mapping the fast fanfare part here, instead of this longer slider it's the perfect part for 16ths or a small reverse slider so the player feels like they're playing that awesome little rhythm that's really unique to the song.
01:30:366 (1,2,3,4,5,6,7,8) - This pattern seems a little smashed together and kind of awkwardly spaced, but I don't know how you would really fix it.
01:46:116 (1,2,3,4,5,6,7,8,9,10) - This part is pretty unimaginative. The interesting thing about this map is that it goes from high speed jumps to this kind of stuff extremely quickly, which isn't really a good thing. The map seems to change styles at every section sometime. You have a very flow-y map with very little sharp directional changes except for a couple places, so the "jumps" of the map come out of nowhere when this kind of pattern is the usual style.
02:18:366 (1,2,3,4,5) - There's zero reason why these sliders change speed. Makes this stream section that much more confusing.
02:23:366 (1) - Starting right here I would much rather just stream this normally, with circles instead of sliders. The sliders are incredibly annoying and difficulty to deal with when trying to combo, since at 240BPM it's very easy to let go too early and get a slider-break. If the player has been able to stream 240BPM for the first 3/4's of the song, I'd say they can stream 2 more sets and not feel too bad about it.
03:03:366 (7) - This should start a new combo.
03:04:366 (1,2,3,4,5,6) - Like I said in that last big paragraph about jumps, this pattern here comes out of nowhere. I'm partially complaining because I can never hit it because I'm bad, but at the same time these jumpy parts come out of nowhere in an otherwise very linear map that is more about speed and dealing with the 240BPM and streaming rather than jumps.
That's my two cents again, feel free to message me in-game if you have any questions regarding any of this. Again most of this is my opinion so don't take it as fact.
