The game's concept is wonderful and could have been explored more considering you didn't make full use of the 3 hours. The area where the player interacts could be way smaller since we don't use most of it. The puzzles were very cool, and although easy, I don't think that's a problem considering the time constraints. The music could use some work specially in the "popular royalty free sound effets" department. There is a website called https://freesound.org/ with millions of royalty free sound effects uploaded by users.
