This felt like such a great run, really couldn't believe the time at the end as my only other completion was over 15 minutes.

I use the improved route for m1 to get a big PB. After grabbing blue key and running back to TP and teleporting, you can run out a bit to raise stairs so you don't have to wait for them to raise later. This also provides a faster route to red switch after the red key grab, but I decided to skip it since there were so many enemies on the stairs.

M4 went really well considering how many spots your jumps can get blocked.

M6 platform raised for me which saved a chunk of time.

M7 is probably my weakest level. Very sketchy starting with 1% health but I keep a good pace still.

M8 was unexpected. I didn't even know it was possible to 2-shot this boss so I grab extra health, ammo and armour.
