Thanks for your mod~
I am pretty thorough, so don't be annoyed if I point out a lot of issues. A lot of times they are just my opinions, so feel free to object to them. :3
d = don
k = katsu
D = big don
K = big katsu
... Kinda regret taking this request now, I have pretty much nothing to say. Mapset's very polished, especially the Oni. :3
00:01:473 (1) - like Muzu, you sure you don't want this to be K? It is not as stressed as 00:04:139 (15) - , so k would be enough imo.
00:22:306 (126,127,128,129,130,131) - I would actually prefer this to be ddd ddk for two reasons: changed to ddd kdk instead.
1. 00:22:806 (131) would then be k, matching vocal's high note as well as being consistent with 00:23:139 (134,136,140)
2. The entire phrase starting from 00:21:806 would have increasing density of k notes, leading into 00:24:139 (142), the start of the next phrase.
01:01:639 (327,328) - reverse, change to kd; k would match vocals, while d would match the slight pause in the guitar I think d k would result in a smoother flow since the distribution of kats is more even.
01:12:305 (409,410) - ^ same as ^
And that's about it! Nicely done, I like both your difficulties a lot. Hope you find this mod helpful, and good luck beatmapping! :3
