Well done! I really enjoyed playing!
The orange footprints getting close to me and then just leaving if I stay quiet is such a good detail.
Just a minor detail as feedback: The first couple of levels had many perfectly rectangular walls. I think it would add a lot of flavor if the walls were more irregular or had irregular accents (at least visually) to better represent the cave. The same goes for the death zones and the water. It felt a little weird to "see" perfectly rectangular death zones in a cave. I don't know if the player would be able to walk as freely if the death zones aren't rectangles though. Would need playtesting I think. Just a thought.
Amazing work!
