It felt like a really fresh twist on Rock Paper Scissors, with a few new gameplay mechanics, except you can see what your opponent is doing, and there is a knife that beats almost everything.
It feels like a rhythm game because you essentially need to hit the key at the right moment.
Once you get into the game, you know that fire works on rogue and the blue bubble works on wizard, so you basically wait and press the button with the right timing. And yes, the rotation gives it a beat.
