Very nice game! There are a few games in this jam that are based on the same idea as yours, but this is the best implementation of it that I have tried so far. It feels very good gameplay-wise and the graphics look super cool. Especially, the animations are great.

I would have loved to play some more levels. If you want to keep working on this project, you could maybe think of another game mechanic to make the puzzles more complex and challenging.

Also, the user interface looks nice. Only the end screen was missing a button that allows you to quit the game or go back to the main menu, in my opinion.

Overall, this is one of my favorite games so far (and I already tried like 60 of them). :D
I really hate that I can't give you any points for audio.

This was great! The art style was really fun and consistent, with cool animations. The dying/respawning mechanic worked well for the puzzles, and the controls were intuitive. Personally I would have liked a little faster movement speed, but that's just personal taste. The only real downside was the lack of music or sound effects. Definitely worth playing!
