Ambiance is really cool, and a neat concept to bring colors back to the world! Quite a bit of content for a game jam game, and new mechanics introduced at a nice pace (plus introduced with detailed explanations).
The info screens feel a bit abrupt and on at least one occasion I hadn't finished reading when it went back down. For fooling the player - having the outlines sometimes not appear feels unfair/not great from player perspective, as did a lot of the hidden pit rooms. Definitely felt more like a rage game, which I don't have much experience with / not my typical cup of tea, so it's hard to give constructive feedback.
