Really well done game! I think the platforming was well designed and the art is pretty well polished, great job on the animations. I was worried that the Tetris part would just be an afterthought but in the later levels, I was forced to plan where I was going to put my blocks. I think a fast fall button or something could help with some pacing issues. Right now you swap between platforming and then switch to a slow Tetris. A way to reward fewer block usage could also be interesting. Overall though a well thought out game, nice job!
