This is insanely well done, one of the most creative mechanics I've witnessed in a game jam. Like it's seriously so good. The level design possibilities are endless.
The only project so far that I've given 5's for both creativity and enjoyment. It's a shame it wasn't winter themed because you would have knocked it out of the park.
This could become a high quality mobile game for sure. Might be a little shallow for a desktop release.
