Badass!
Graphics were good. Your animating style was always sort of peculiar, as it looks like you use the line tool for your sticks... Nevertheless it was pretty smooth. The interface and other graphics were well done too. The red death line was kind of unnecessary; once you fall off you're pretty much done for, so you could have made it invisible.
Sound was pretty sweet, as always. Good rhythm, melody, and timbre. Didn't get repetitive after a while, either. Would have been nice if there had been sound effects, especially for the blocks falling into place.
Great gameplay... I had a lot of fun playing it! The squishing script wasn't too sensitive, although I 'died' getting hit on the back of the arm by one of the blocks, obnoxiously. There were a couple glitches, too, such as standing halfway between a block and dying if you moved, or dying while walking into a few corners. Other than that, the randomization was pretty good, especially because every piece fit perfectly. I would have preferred if the arena had been a bit wider, and if there had been walls instead of a gaping abyss, but that's preferential stuff. It could have used more depth, like powerups and stuff, or a highscore board in particular. The medals were a tad generous, as well. I also disliked using J and K for the commands; it would have been nice if you could use A and S instead, since most people are more comfortable with those; maybe even customized controls. Other than that it was pretty good.
