Haha, I was thinking of procedurally generating the levels but I decided for a jam it may be best to stick with pre-made levels. Good idea though! Might expand on it after the jam.
I've seen your game and your updates and they look really interesting! I'm looking forward to playing it and working out how to play it! Can't even begin to think where one would start when making a puzzle game.
I've just imported some effects from bfxr and it's been really successful. Good luck!
