This is a really creative take on the jam, I don't think I've seen this interpretation before. It's quick and easy to learn how it works, and the puzzles are actually really well designed and forces you to think. I really like the visual effects and it looks very nice.
The only thing I would say is that the gameplay does get a tad boring after a bit; adding some new puzzles mechanics throughout the levels would be nice (Things like rotating blocks, etc.).
I really liked this one! Good luck on the rest of the jam!
