I really enjoyed the atmosphere, and conceptually it's super cool, but I also had a great deal of trouble with the physics mechanic. The level design also felt set up for failure. I made it to the far first right wall, up the wall, and across just to land in that little hole and have to restart.
I think it could be great with just a little more time. I was immediately invested with the narration, but unfortunately I never got to hear more.
