Nice submission! I like that the theme played a role in the mechanics, though more would be better. I may have missed the part in the tutorial that said the light would reveal secret passage ways. Since that was such a critical part of the game, I would have liked to have had a clear example ahead of time. I also found the control scheme unintuitive, and felt like I was fighting it to do what I wanted. The level design was good, had a nice progression, while also allowing for different strategies to dominate in each one.
Good work to the team!
