A little and colorful puzzle game!
My main worry with it is that it's probably impossible to play for colorblind people. It's sorta understandable for a jam game, but keep that in mind if you intent to expand it.
On another note, while colorful, it's hard to keep track which cube is emitting which laser. From what I understood, the colored wall means it's emitting, but its still a bit confusing. Maybe having different sprites on the emitting/impact point of the laser would help.
But overall I had fun playing, and it has a decent amount of levels for a jam game. Good job!
