Excellent music. I also appreciate the narration. Potato mic has its charm, but it doesn't deter from how well the narration works here. It already has been said below, but Portal/TSP vibes from how the narrator has his emotions laid out. The game kind of led me to believe there'd be a second ending for dying after he told you to go.
The puzzles are a bit.. rough. Early ones are good, your run-of-the-mill getting you started with the controls, but some of the later ones are less about an 'a-ha' moment and more about just memorising the steps. One of the levels I don't think I figured out the solution at all because of it.
