Very nice game. I love how you implemented a shortcut for the platforming section. The puzzling felt good even though I sometimes wasn't sure what button would do what and if I would need a box to activate it and sometimes only specific boxes worked.
The camera is a bit hard to control and clips into the wall a lot and I think maybe putting the "grab" on another key than right mouse button which is for camera would be nice. All in all really cool looking game with a great ambiance through the lighting, well done!
