I never thought I'd play another rythm game, but this somehow hooked me!
Being able to remap the controls would have been awesome, for using something like asdf or 1234 with one hand, but dfjk also worked fine for me.
Sound and graphics were very good an fitting! Altough I think the third level could have adapted a bit more the the rythms of the song. (Though it must be unbearably hard to implement the patterns into the game, I guess...)
Glad that I played this game. Well done!
