EDIT: Forgot to state this elsewhere but you need vsync enabled for this game or mouse turning is just impossible, which is why I'm actually humoring load removals for once.

LOADLESS TIME: I went by the first frame the loading screen image appears, to the frame it disappears and the screen goes black.

LOAD TIMES: INTRO: 00:05.850 LEVEL 1: 00:15.867 LEVEL 2: 00:07.800 LEVEL 3: 00:08.000 LEVEL 4: 00:15.167 LEVEL 5: 00:14.567 LEVEL 6: 00:05.867 LEVEL 7: 00:08.150 LEVEL 8: 00:08.550 LEVEL 9: 00:08.800 LEVEL 10: 00:07.400 TOTAL: 01:46.018

(Milliseconds being ignored for runs at this time besides calculating for loadless time; there's room to spare lol)

Probably one doesn't even need the level 3 stealth pistol (could go for the normal pistol near the start of level 2 instead), but it is (in theory) a good safeguard against any nonsense in level 5. Levels 7 and 9 are ugh, and obviously the 3rd boss is a crapshoot. Level 10 I was least prepared for, as there's much about the event triggers I'm still confused by.

Basically I only know you can cheese the final boss into going to their death position by skipping at least one of the triggers in the area and blasting them from below. Not a very good run, but a decent starting one for someone to improve upon. Glad to finally have gotten this game off my speedgame bucket list after 4 years of knowing about it (yes).
