Made it to level 2 before quitting and can only echo some of the points others have already voiced. Checkpoints and/or a life system would have been nice, as replaying the same section over and over again gets annoying real quick. It only made me rush through the level even quicker, often ending in killing myself (as the flame) by falling into water I could barely see when starting my jump. And yeah, clearer feedback on triggering a switch would have been nice: I spent a while smashing the first switch before realizing it had already switched. Other than that: Very solid entry! :)
