Neat idea. I like the speedier parts of levels combined with the slidy movement. It reminds me of Super Meat Boy. While the explosion SFX were a lot louder than anything else, the general variety of SFX was nice; most things I expected to have a sound, did in fact have one. The art looks quite good, and I especially like the shockwave effect. Level-based games seem weirdly uncommon in game jams; it's always nice when I come across one.
Cool submission.
