I'm gonna comment on this one so I won't add unnecessary bloat comments to your guide, but your guide was really extensive! I can see that you put in a lot of research and that you have a lot of knowledge on this type of game already, wether it's traditional fighting games or platform fighters. For example, you correctly understand that the small attack are often way more important than the big attacks, for example with dragonfish's crouch attack. and you also figured out an advanced movement tech in Dashjumping
I'm going to add some comments under there to make the list even more complete, cause a lot of these things you had no way of knowing. If you want me to delete them so you can update your own list, let me know. it might be a better read that way.
There's also a really important mechanic that I don't think you mentioned anywhere, but you can parry attacks by releasing the crouch button (there's a half second cooldown after a failed attempt, but if you parry something, you can more quickly counterattack and you get some pepper meter). this is a good counter to most projectiles and you should always keep it in mind if you're using projectiles from far away.
