Interesting concept here, I thought. The game doesn't start off with a handful of easy levels to teach you that concept, but instead throws you right in at the deep end with you needing to switch the light mid-jump at least twice to complete the first level. This is probably a good thing, on balance, but it feels a bit challenging at first! However, it's also made difficult by the collision detection being extremely unforgiving, which is frustrating; the slightest whisper of contact with spikes is instadeath which means a lot of adjusting before a jump, which isn't fun so much as frustrating. Nice idea, though, and I see you're already suggesting a future change to the hitboxes which I think would solve the issue and be most welcome!
