Got rocked a bit by Greater Nightmares (but took only ~300 damage in the second runthrough without potions). Cut some corners on the way out; let a few headless hit me, etc, hung around killing Oozes on Feel the Power to get another Carnage Point, and left the pyramid at T+9:20 (3:33 PM Sunday).
No Hunsinger's treasure, and I had to scrape just to get 80% accuracy (turns out the game rounds down in _all_ instances, be it 79.995% or no)...so there's room for improvement.
Also, Wrong Way! looks a little weirder once you've set the bomb. Or something.
