Hey, really cool game, the lighting was a huge plus, that combined with the music made the game really surreal. Really great job!
The use of the button limitation was nice, although I kept forgetting the controls as I played (not much you could have done to improve that though to be honest).
Very tiny note for improvement: make the music stick around between scenes, the immersion is jarring when you switch and the music restarts. (you can do this with Object.DontDestroyOnLoad in Unity).
Overall really nice!
