I played it once, died, and then on my second try became an immortal speed demon, who could not die, and my score hit -10000 but still I ran, spamming the living hell out of the space bar and accelerating into a new dimension. The darkness had nothing on me - it would fill the screen, and then get cast back to the left again. And then I hit a wall, and just beyond that wall was Minecraft Steve standing there with a Minecraft cake, and all the monsters that had been chasing me got stuck just behind me, so I could not continue, but I could not die. An eternal purgatory.
On a real note though, very buggy if you spam the space key (everything said above, whilst mentioned in a dramatic way, did actually happen, even the Minecraft Steve bit (why is he there??)). It was fun, and the graphics were nice, it just needs some problems fixed I think :D
