This is a super neat idea, and well executed too! I have played a lot of game similar to this before, even ones with forced commands along the way, but I have never seen the permutation system in any other game before. This made the puzzles way more interesting and really forced me to think about every single possibility. A lot of the solutions were really elegant, although I think I might have cheesed a few levels based on the simplicity of my code. The visual style and audio work really well together too. I could honestly see this doing well as a full game if you ever decide to build on it and add more levels. Really well done, especially in such a short time frame!
