I enjoyed the variety of challenges in this game, and the way the difficulty scales along. The first level serves as a nice and simple introduction, allowing the player to quickly understand how each of the levels work, whereas the second and third levels offer unique puzzles for the player to overcome. The appearing walls were very cool to see, and made the chase in the middle of level three to be thrilling. However, I noticed that enemies end up turning down over the player on contact, causing them to trap the player in a weird way until the player manages to get away from them. I felt like you could've used the health system in more ways too, maybe adding a projectile trap that hurts the player but doesn't directly cause a game over.
