I love this game. It actually has a lot of parallels to mine :). The light mechanic is great and the levels are well designed. Normally I would say the jump is a bit too floaty, but it actually fits the mood of this game perfectly. My only two suggestions are to make the follow mode a bit faster so that you don't have to wait for the light to catch up, and to reduce the size of the spike hitboxes slightly to make them a bit more forgiving. I got a bit stuck on the nearly-blind jump at the bottom of the last level, but I eventually worked it out and got to the end. Great visuals, sound, and overall polish. Excellent work!
