Intriguing idea! The rule discovery process was pretty smooth. Initially it seemed very confusing and random, but bit by bit the rules were revealed (and the codex definitely helped!). Also, good job on the art and sound, the ambience they created fit very well with the concept! One small bug, I couldn't collect the last codex page (bottom right corner, for me). It didn't matter in my case because I managed to beat it right after that, just thought I'd let you know.
