Cool concept and art style choice, puzzles are unique and interesting with a great possibilities for extension. But I would say that because of such limited color schemes and simplicity of game symbols it rather difiicult for a new player to get into gameplay. For a few minutes I was just trying everything possible to understand what is going on. It isn't so bad in fact i would say it's right to make players learn how to play the game by their own experience, but in your case first minutes was a bit confusing. For example, you explained how jump and color swaps work, but why would I teleport by touching rings? Now I hopefully understand mechanic, but by that time I saw that I constantly returned to spawn point as if i died.
