Very cool looking game. It's really impressive that this was made in only a few hours.
The only thing I was wondering if procedural levels work that well for a puzzle game like this. I mean, some of the levels were almost completed as they loaded in. Also I wonder if it is possible for the game to generate an unbeatable level?
Also the music is interrupted after each level?
Edit: one thing I noticed was that the level was over immediately after the puzzle was solved. Would be cool to add a delay to the next level loading in, with some cool effects for showing the completed level.
Anyways, great entry for this game jam!
