8:28.52

Thoughts on the run:

Intro: Standard. Could save 0.5s by doing the parkour faster W3: As close to perfect as can be hoped for. Getting the 3rd BLCJ in one try would save 2 seconds W2: Cube Driver should have been saving time not losing 9s. Static Vexer could be 2s faster with a slow slide instead of fast slide. Rest was pretty average W1: A few very minor stumbles in So Close, So Far. Rest was as close to perfect as can be hoped for. No idea why I reset in Through a Window at the end. W4: Press and Jam nozus were messy, could save a few seconds there. Could save a menu at the end by doing that jump at 30. Terminal: Lost 1s to nerves. Don't do that.

I think up to 20s of timesave from here is possible without scouring for microimprovements. Getting to sub 8 would probably require going for some insane/fluke BLCJs in W3 and W2.
