Best time of 585 resets and 9 hours of fails including good non recorded times.

Got 1:03 IGT with a No Stairs Route, manipulating the 2nd floor enemies to get down. Its a very tricky to do and not always work but almost i know the basic to trigger it .

And got a 1:06 IGT with stairs route ..

Maybe the sub 1 min its possible ?

I think yes.
