Maybe when you're mousing over a color in one of the dice sides, it can outline all the sides that are part of that color? Telling the difference between yellow and slightly brown yellow was kinda hard. It's also help colorblind players.
The shaky gun is annoying. It does nothing except screw over unlucky players. Russian roulette has enough luck involved to not need such a stupid mechanic.
I got a(n) S on hard! My score was 4292563 with a max combo of 357. I scored 308 perfects, 49 greats, and 0 goods. I got only 0 bads and 0 misses! I was playing on 4.5 speed and had 0 crazy options on.
Sweeeet! I need moar of this game though. 4 Songs ain't nearly enough. Makes me want to play Beatmania again.
