I have to say that this is one of the best jam games I ever played. It fits the theme very well, the simple visuals fit this type of jam and help you focus on the puzzles. The music and sounds work for the tone of the game and the mechanic are easy to understand, yet still assist in creating challenging puzzles. If I had to give some criticism, I would say that respawning should be a lot faster, and that the difficulty spikes around level 5. Besides of that, really great game and I would recommend for you to work more on this game, you can easily make a dozen more levels just with the existing mechanics.
