I like the concept behind this game, I've seen similar color-based platformers, but it's not so common to affect my score. The jankiness when you die and are reset to the beginning was rather unpleasant.
Some of the deaths seemd unfair, when things were moving on the screen, I seemed to die before I hit it, maybe a result of the aforementioned jankiness? And when standing on the fading blue platform, the guy jumps when it disappears, so if I've painted too high at the end, I can't wait in the middle of the platform for it to fade away.
