I managed to get the time down by moving the game to my SSD for improved loading speeds. I also found out that you can press enter on the exit window before it has appeared.

Mod Edit: Retimed according to the new Any% timing rules.

Time starts at 8.400 and ends at 8.733 at 60 fps to get a final time of 0h 0m 0s 333ms. Retimed using yt-frame-timer
