Thank you for the game!
The visual craftsmanship is of the highest quality! I particularly liked how you managed to avoid all UI elements. This, combined with naturalistic lighting, rich texturing and great music created really cinematic experience. 
I wanted to write that lack of some of the traditional formal game elements, like results or winning conditions, made this game feel incomplete. But instead I will say that their absence enhanced the 'nightmare-ish' theme of the game very well.
Great job!

I tried running the game three times. On the first try, I could hear the music, but the screen stayed black for a while before the game just stopped and quit. On the second try, the ball on a crumbling bridge appeared, so I pressed w and d to move the ball to safety. Instead the ball went toward the camera, then curved around toward the direction I was trying to move it, resulting in falling off the side of the bridge. The screen then went black and stayed that way. On the third try, I waited until the ball had been on the screen for a moment before trying to move it. It moved in the correct direction, but because no combination of w and d went straight and there was a lot of lag, the ball fell off. At that point I hit alt-f4 and stopped trying.
