I completed this game. There's no tutorial in the game, but I quickly figured it out, which is a plus. It's a fun puzzle, but the final chapter was easier than chapters 3 and even 2. And at level 11, chapter 3 got stuck for a long time.
Yeah we didn't pull off the jam balance quite right for the final chapter. We've actually just uploaded a 1.1 version, which revisits that part, among other things.
