The game is fun and challenging, I loved the puzzles. I really liked the pixel art in the levels and the music was nice, the sounds were good as well. And the options menu was amazing :D
I very much enjoyed the game, and with more levels the game would be better but of course we were working with a time limit xD
Good luck in the game jam!
Important Note:
I played the web version and there were a couple of levels which were unplayable because part of the level would be hidden on the sides of the page. I was able to fix it for myself by editing the page code a bit with Google Chrome, but I think the best solution right now is to edit the game page to show the unity full-screen button, and recommend in your important note to play in full-screen.
