Genius game. I completed it, but I'm embarrassed to say how long it took. I'll just say that this is the jam game I've spent the most time in. If I replayed it I still wouldn't know how to solve it, and I still don't know how you made the puzzles. If you overlap all the puzzles, it still wouldn't help because all of them can have a different state. I'm just thankful that the recursion didn't exceed 4 times or I wouldn't have made it past the first level.

hi! Puzzle design is something we put a lot of thought into, and as with most puzzle games (here especially) the best way is to start from the solution and then work backwards. So for a lot of levels we started with a set of inputs that we want the player to do and then design the level to force that sequence. Each step of the recursion further restricts the possibilities.
I’m really glad you enjoyed the game and completed it!
