Really good and fun! It's a neat concept.

That's some good stuff right there! I liked how attention was paid to little details without losing scope of the jam timings. Little stuff like how the player square oscillates when you're trying to push against a wall, that's a super effective feedback. Also I'm stuck on lv 5 ;_; I'm gonna finish all of them today though ^^

This is a really interesting game.  I'm not sure if you planned to replace the squares with sprites, but it kind-of works as it is.  It has a very clean look and the game feels complete with animations, sound, effects all working together in a great way.  I did get stuck on level 8 at the end with the exploding box, but I loved the puzzle level design aspect.  The transition effect between levels looks cool too.  Amazing work in such a short time and starting late.

Really cool design and sounds… Controls a bit weird but you can get it after playing for a while (1-3 minutes). I like it :)

Good Job. Like the gameplay and difficult level of the game.  Movement felt a bit unresponsive sometimes when you had to do quick turnarounds. Took me a while to figure out what squares did what in the game. Made it with 27 deaths.
