Defeating Silva gives you access to an insane amount of upgrades
I'm playing this game for the first time and have gone in completely blind, currently just beat Ulv so no spoilers please!
Maybe this is a known thing already, but I discovered that getting Silva essentially gives you 3 extra jumps if you use the charge attack between each jump/dash.
I'm not someone who usually looks for sequence breaks in MVs, but I've been able to get to so many places that I feel I shouldn't have been able to. It almost felt intentional until I got the wall climbing upgrade and realized I don't think it was 😂
Anyway it's been fun to see how far I can push it; I definitely see the appeal of the sequence breaking/speed running stuff that people do now.
