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.
