I like the idea of colour cycling and how you take advantage of the order in the level design to create interesting levels. Difficulty ramps up quite quickly though. The wall jump also feels off... Notably that it forces you away from the wall without you having to hold away from the wall, and that tapping to move away from the wall even slightly before pressing jump causes you to be unable to jump. That's not bad design in and of itself, but it is contrary to the way wall jumps are done in most games, which makes it that much harder to learn.
