I was wonder if I am a totally noob on rythm games or somehow it is so hard to understand and to battle against the demonesque, after reading the comments i fell better.
This game needs some instructions, but first it needs ballance on the devil's dance fight, it's so quick i fell impossible to win, I think that speed could be increased as you win to make it harder and make the player feel is advancing. Sexy devil there I like her movements.
