The Dark environment reminds me of Limbo. I like the fact that there are very few hints, even though I struggled with some puzzles for a lot longer than I'd admit.
Some suggestions I'd like are a Short Animated Intro to establish how we ended up here. Also, the option to rotate images but not one had anything on the back, was kinda bummer,I kept hoping for a secret.
Player and Camera Movement felt smooth.
solid 9.5/10
