You managed to create an inmersive atmosphere with a very interesting puzzle mechanics. At first I thought that everything resetted with the clock, but you made a very good job showing the player what to do whithout really telling anything.
The only tiny advice I could give is that I could not change camera sensibility. If you decide to continue with this project (which I encourage) it would be nice to have a "settings" option to configure that and the game music/sfx volume.
Congrats for your project, its a very nice one!
