nice work ! during the jam I wondered if someone would interpret space in this way ^^ 

This is a cool puzzle game with impressive procedural generation! (i'm assuming the puzzles are procedurally generated) It seems that at higher difficulties, the puzzle is more complex and you get less time, which makes it oftentimes pretty much impossible to solve. I would definitely come back to play this again if the higher difficulties had more time, and if there were even higher difficulty options.

good idea
