Finally got that 3:22! I use a different strat for the final room than in my previous record, because I feel like it makes the final clip more consistent (because you are always climbing up from the ledge and are therefore in the same position every time).

Really happy to finally get a run with no major mistakes, though I estimate I lost about 0.8 seconds due to taking it safe in some levels. On top of that, close to a second can be saved by skipping the ammo in the final level. I picked it up just to be safe because I figured I'd still have a shot at PBing if I would waste a bullet at the very last clip. But seeing how close it actually was, that probably wasn't true. I'll keep trying for that 3:21, which is probably as low as this run can realistically get.
