This game has such a solid and cohesive design and it's wonderful. The atmosphere of it is also incredible. It's also a very unforgiving game, every puzzle seems designed to get you out at exactly 1 oxygen which means there is 0 room for error, this led to a few frustrating moments where I hit the wrong direction and then instantly was like alright time to restart. That might have been alleviated if restarting was just a BIT quicker to do.
