This was a solid platformer submission for the jam, so good job throwing it together in time! Especially if you worked on it alone. Personally I wish the light/bones mechanic was explored more in terms of gameplay, as right now it just feels more like an aesthetic feature rather than something that affects the way the player has to play the game. Beyond that, I also wish there was an options page to lower the volume or that it had been considered as the music is nice but very loud. Overall, I congratulate you on your perseverance to get something out! Good luck in the jam!
