Run could be optimized a bit further, made a few blunders here and there but I think it's alright.

Don't mind the random "Flying is disabled" that pops up midway through the run, I accidentally pressed the fly key while mashing WASD.

NOTE to mods: The in-game timer shows 3:29:06 but this seems to significantly drift behind the real ending time by about 10-15 seconds approx so please amend it accordingly.

Mod Note: Adjusted to 3m 41s 660ms after a frame by frame review.
