Very cool, love the idea of rearranging light to solve puzzles like that. I did get stuck pretty quickly. After the first stage when I powered the church, it seemed to glitch out loading the next area, and restarting the level left me in a state where I couldn't seem to progress as well. The arcade machine was a really nice touch, and I really dig the aesthetics and music.
Nice work, I would love to see this expanded on!
