I'm enjoying putting this together so quickly! I'm not too worried about the artwork and I kept the state machine for the player(s) sleek, so they're pretty much completely done on that side (unless I want to add a visible trail to the Night - which I'd like to do, but might take too long).

I can spend the whole day tomorrow putting together a few puzzles; maybe even a monster. I'm considering that the real challenge for myself; how quickly can I put together some good puzzles with this game mechanic? Does it have enough depth to fit into a real game?

It's kind of fun to play with even without anything to interact, so that's good.
