[Insane]
02:04:026 (2,3,4) - This kind of positioning can really throw the players off, i recommend adding the 3rd note on these sequences into a new combo (repeat for all sequences like this and for example 02:49:025 (1,2,3) this one) since the first and second notes jump, but it can be hard to tell if the 3rd note will also be included in the jump since it's in the same combo, so a player may hit early.
[Muya's Hard]
Pretty nice map, nothing to complain about however
00:09:564 (5) - Maybe add an extra note after this, or turn this into a slider to fit the lyrics better? since it looks like it was what you were aiming for here (repeat for the other parts in the beginning that are similar if you do change).
[KSHR's Normal]
00:02:180 (2,3) - I think you should probably add a note in between those or use the sliders in a different way, I keep tending to click (3) early due to the music (or you could unstack them, maybe that's what is throwing me off)
00:40:487 (2,5,2,5) - Not sure, the timing on this can come as a surprise for players, but then again is not the easiest diff so i'll let it pass.
[Easy]
01:43:256 (1,2,3,4,5,6,7,8) - Combo too long for an easy difficulty.
