This game is incredibly dull. The controls are a little awkward, and the angle the body floats at is strange. Whatever message is behind this thing, I frankly don't care about, and it really poorly explained. All I can get from this is that space is apparently cylindrical.
Graphics feel slightly inconsistent. The transition from the top to the bottom of the cylinder is jarring.
There isn't any gameplay, it's immensely boring, there's no replay value, and I get the impression that there is a message but it is put across terribly. And I'm not sure I want to watch a 40 minute video figure it out.
For a game with a message to work, it needs to be put across both clearly and enjoyably, obviously that's tough.I think I can see what I think you're trying to do, so I'm not going to give this a rating, because it's trying to be something other than a game, in a way that I can't properly appreciate.
