Nice visuals and idea but the platforming feels a little rough. (Catching on the sides of walls, etc). It also feels like the light mechanic falls a little flat when you can see all the platforms without it. (I suppose that will depend on different monitors but on mine it's not hard at all to see them).
Regardless, I think you did a good job for a 3 hour Jam! The main menu in particular looks nice and polished.
