I... don't quite get it I'm afraid?
Walked around for a bit, collected... floating paper bags? Every time I did, the textures got a bit more blurry. At like 800 it was very blurry and game ran very badly, like... 10 FPS maybe?
Eventually, I ran into a dude, just standing there. So I poked him and... something happened, distance went back to 1.700-ish, but my scored stayed the same. Did I die?
There's some lighting bugs which sometimes make going through doors very bright.
But hey, a 3D game in 2 days, that's a lot more than I can say I managed, so kudos! :)
