Sorry, but this does not count, you have the WR for backwards run, IF you can provide video evidence. THIS IS NOT A ANY% RECORD. THE RECORD FOR ANY% REMAINS AT 23.
I'm confused on how a backwards run would be timed? Evidently the entire run can be completed without even starting the timer, so it would need another separate timer, which would be redundant. Any% counts because 1, there is no official categories, and 2, any% includes bugs, which this is one.
Until there's official rules by either speedrun.com or by the creator, I'll consider this the fastest time anyone has achieved.
