Just had a look at the run that was denied. KenE (2nd place) and I had a look and came to the conclusion that he must be speeding up the game or slowing down the clock, as he messed up several times but still came up a couple seconds faster. Hopefully if it wasn't cheated he can do it again with a proper setup. I know it sounds terrible.

a guy tried to submit a run that was claiming to be #1 but it had no sound, a big watermark and what looks like an external timer. also the windows of the game wasn't fully on screen so i denied it for being far too suspicious.
