Thinking of running through the game, wondering what the rules were? Can we use skulls? What difficulty? are my main questions

Also can you add a co-op option as well? I'm sure it's barely any time save but has minor potential to be and I know a friend of mine would love to run it with me

I updated the leaderboards with the information. Difficulty would be easy for Any% (you could do it on another difficulty if you want to though). No skulls since you start from New Game. Time starts when selecting the difficulty. Time ends when the timer at the end of Hold Out (the final level) reaches 00:00.

I have yet to play Co-op so I don't know what the menuing is like when starting a new game but if there is any problems with the above rules then we can update your time for the run accordingly.

Let me know if you have any other questions.

Good Luck!

Awesome thanks a ton, just to clarify though, what about skulls in individual levels?

No skulls in any current category. If you would like to use skulls, I could make a separate category though I'd rather not unless there is more interest in there being one.
