Ahhh current osu hitsound system is only good for percussion sounds. Tried to mapping osu mania map with various hitsounds other than percussions, like guitar sound or piano sound or something(of course since I'm no professional in music, so my samplings are really crappy, lol. I just wanna test something technical.), and the result was quite painful. At least it would hane been much better if setting hitsound-set for each note was woking properly, but unfortunately whenever I used that too much, it got break in testplay in gameplay. Also there were some irritating bugs in osu mania editor...
Well but if we play osu mania with proper maps, the gameplay itself is pretty fine, I guess.
