Went in expecting a rhythm game, and got a puzzle game instead. I was pleasantly surprised. I see you said Rhythm games are hard to make, but I don't think this would count as a rhythm game, even though the moves happen to a beat. Very interesting game, but a bit frustrating that it seems like enemy attacks seem to be "alive' for 2 beats instead of one, but it's okay. I really liked this :)
Almost forgot to mention how cool the intro voices were. The only thing I actively disliked was the graphics, but the game was really good. fun to play. Bit hard to start, but satisfying to figure out, so probably a net positive that it's hard to understand at first.
