There are a few main ways to go about ASA - I'll put each of them in in order of difficulty

Sign Skip

• This trick is NOT doable on the PSN version - there is another proxy for that that I'll dig up at another time and provide.

BEGINNER: Next Cutscene Skip (Death Abuse) + OOB

• This is the Beginner level method of traversing the level

INTERMEDIATE: ASA Void Drown

• This route costs ~15 seconds in Paris to setup getting the charm but also saves a hefty amount of time over the standard skips above

INTERMEDIATE: ASA Void Drown V2 - Oggy's Setup

• This is another method of the ASA Void Drown that works on PSN and seems a bit more consistent.

ADVANCED: Periscope

• Honestly, don't go for this until you're going for world record - this is easily the most difficult thing to attempt in ASA, and while it saves a solid 15-20 seconds from Void Drown - it's much less consistent and much more finicky at the time of writing. I'm honestly not entirely sure how to explain it well.
• This is a setup that Snugggles uses to get a little bit more consistent with the actual landing position
