Very interesting Idea! I could imagine that this can become a great game when mixed with something like an interesting narrative like in games like Portal or the Stanley Parable.
The mechanics seem very fleshed out and work great together! The sounds and music are nice. Neither too loud or too quiet. They have something funny, yet relaxing tone . Loved it!
It would have been great to see a bit more art in the form of textures, and colors/lighting. But not a big deal.
