Pretty cool concept. Reminds me of a rotoscoped game I used to play with my cousins. I liked the basic game mechanics and the art style was quite fitting. Controller support would make it even better for people not used to keyboards, especially once you've unlocked the wall jump. The floor was a bit too slippery near the edges (a problem I often had to overcome when making games in Unity due to their physics system, it's easy to make the ground seem icy). The color changes were a nice touch to diversify the areas without having to create more art assets. A fun game overall and an excellent example of building a good game around a couple of simple game mechanics. Nice work!
