[Easy]
0:18:931 (1,2); 0:29:597 (1,2) - these notes sound a lot better when you've got a whistle only at the second ones, I guess.
[Normal]
0:44:764 (1) - that new combo ain't necessary, I guess.
1:03:931 (1) - ^
2:02:097 (1) - ^
2:21:264 (1) - ^ even though I see that there's increased spacing a bit.
2:49:931 (1) - ^
3:19:931 (4) - maybe add a slider at this point, like you did before at the parts in the song like this one?
[Hard]
AR-1, plays A LOT better.
3:23:597 (1,2); 3:34:264 (1,2) - I don't really like these, you can absolutely come up with something better : )
[Insane]
AR-1, plays quite better, especially at HR. also, since you already listened to my QQ about "Y U NO USE AR5" we already discussed about the circle size on that difficulty, I'll go straight to my little suggestion:
0:28:431 (3) - maybe shorten it by 1/2 and add a note at the white tick? sounds a lot better like that.
well, I guess that's it. I can proudly say that it's easily the best map of yours, lolcubes :3
good luck!
