You should really polish this, it's a lovely concept and has a lot of good ideas that maybe weren't executed as well as they could've been. It's also a shame that the bugs, though minor, made it far more frustrating to play.
3/5
Muting would be good, like others said. The only other problem I find is that people with motion sickness would probably throw up several minutes into the game. Otherwise, it's spectacular. 5/5
