Hi, cool idea to sync the beat with the light. also nice platformer stuff. but a little bit too hard for me, or at least to frustration for my taste, because you can (but will not always) fall down to the floor if you are unlucky.
The beat/music gets repetetive really quickly, after playing for few minutes. Maybe you can find a "real" song, with a beat which fits your game and timing? there a lots of great songs for free here in the assets on itch.io
well done in this short amout of time!
