What a cool idea, especially with levels where the path is vastly different depending on rolled color. The contrast for the "dark water" was a bit too low I think, but I understand the decision, since there are already so many colors on the screen at any given time.
Some of the levels where you need to traverse downwards are a bit tricky and require a bit of luck and remembering where platforms are, so I wasn't a huge fan of those. Also a quick method of re-rolling the level would be amazing (just to try different paths!).
Great job!
Edit: one more think that I found super funny and ironic :D In the first tutorial level there's a sign that teaches you to use A and D to move left and right, but the sign is in a place that require you to move there, so you already need to know how to move ;)
