Gonna post video examples of new time saving strats, If im posting these, these are likely new finds.

.DANTES FREEZER ELEVATOR SKIP

Never got this in a run, i had the timing completely wrong

.CLIFF MONKEY SKIP

You can just barely squeeze past this monkey if you charge jump

Charge glide at the start of the game, you should be holding the glide button as you close sparks textbox so you're still gliding

Spidersqueeze if you hold right after falling off the top ledge, you should land right next to the spider, jumping past him is easier doing this since his hitbox hasn't had the chance to grow yet

(its mildly consistent but it would still be advisable to practice it using save states)

Wall clip in munitions forge, very hard to get consistently
