Uh, i'm sorry, but I really don't like osu!mania's accuracy and score.
I really say accuracy is way too strict, principally if the objective is making maps possible to SS and S.
Also, if you want to respond me saying that i'm a noob and stuff... No, really, if you think it's not strict, imagine when osu!mania is rankable, the converted maps are reaaaly easy peasy compared to what would be the insane diff on another games.
Also the score seems very WEIRD, principally the penalty for the misses, it pratically makes you restart again and a better play wouldn't get a better score because the better play got a miss earlier.
If everything is fixed, I can even say osu!mania is better than almost all rhythym games out there.
