I liked the concept and the implementation, controls itself seemed somewhat fine for me at least, but the part which threw me off was how so many sections had the colour coded rails on the opposite side. The level design seemed challenging enough that if you didn't keep control you'd bump into walls regardless, so those inverted sections just made things harder. I think having them on the same side as the intended route would make for a much more cathartic experience, and it was there in one or two sections which was probably the most fun parts of the game. But maybe that's just me, other than that it was pretty fun to play!
