Q. How many different types of invincibility are there?
technically, two. one that causes hitlag (respawn, starman) and one that just makes you impossible to hit (shine invincibility frames, spotdodges, etc.)
Q. From which character did the "Ken Combo" originally come from?
falcon
Q. How many frames does Melee's buffering system buffer for?
0
Q. Can you interrupt Ganondorf's u-tilt? (As in Marth's d-tilt interruptible)
no.
Q. Who has the shortest landing animation?
pichu has a landing animation of 2 frames iirc.
Q. Is Doc's F-smash disjointed?
lol this question's stupid because disjointedness is indeterminable. the hitbox is ridiculously small though. do you mean not connected to doc's hurtbox? it's not...
Q. How gay is Marth?
really
Q. What usually causes the "invisible ceiling glitch?"
idk, this question is dumb.
Q. Is Falco's shinegrab on your shield escapable (without DI)?
yup. buffer roll.
Q. How many possible angles exist for an airdodge?
24?
Q. Where is the sweetspot for a Falcon Punch?
the reverse pawnch is like /right/ behind falcon, kinda like his shoulder. otherwise it doesn't really matter.
@ whoever was asking how samus can lose a full charge shot, if she's hit during her up-b she loses it. idk if it applies to her bombs or missiles though. same with Donkey Kong.
as far as shines go, characters with a lower weight than Marth all get knocked down. pichu, pikachu, roy, fox, falco, jigglypuff, mewtwo, young link, game&watch, kirby... all i can think of at the moment.
edit: oh, someone posted the answers earlier. nvm
