I like how simple this game is and how the intuitive the controls are. I felt like the switching-colours mechanic wasn't smooth enough for me to really get into the flow of it, though. I was using a laptop track-pad, which may explain this difficulty. Maybe if the colour-switch function was assigned to the return key, it would be easier to make more fast-paced switches (for example when you get stuck inside a triangle shape, and you need to make a fast-paced switch to make it out of the other side).
