this is just my first parkour replay please tell me what I did wrong and how I can improve

You were extremely stiff and twitchy, it didn't look realistic at all.

It just looked like you flopping around for 1000 frames clicking random buttons.

Don't use grab unless you absolutely have to, and try not to flop around so much. Also using /em chat in a sparring replay makes it look pretty bad.

Thanks

Especially since you used the emote glitch

emote glitch? you mean when you type /em and then just a space? I did that because what I typed was to long

But can you please focus on the actual replay rather then the emotes?
