Nice simple game. I agree with another comment that the delay between being in a winning state and actually winning is a bit long. Same for the post whiteout state and the next level. I'll echo as well that some music would help a lot (they say not having any in their own game).
The puzzles them self actually good but I found the clouds acting a little odd mentally when trying to redirect. Something about the shape and how the beam bounces felt off. Wish I could explain why but I felt more like I was just randomly moving them to get the right angle rather than placing them with direct purpose. Nice work and congrats on your first game jam.
