Other than the trick of my thinking that this is a rhythm game, this is an excellent game. I love how it speeds up, the way it flashes the directions for a couple of seconds, and even just the rhythm aspect (holds, perfect, great, good), and even the fact that I attempted to even get this to work like it was some piano tiles.
Other than those two, the music rocks, though the sfx could be repetitive, the art is SICK (Please teach me your ways), and everything else wraps up nicely.
Hoping to see this be a top 5, top 3 even!
