very interesting mechanic, relaxing ambient noises and the harmony when dropping colors is on point. Needs a bit of polish and more levels, but definitely promising. Just a couple of things:
1- the lenses aren't that intuitive, maybe put an example image to show the player what to do;
2- in very few places, you can see light from lenses through walls, like it stops when it's on the wall but then it reappears a little bit, just a little clipping
