Feedback on simple dash system?

Made a dash system cuz i was bored, not the best copy of This Tweet but its a try for someone who has been scripting for months only i guess (or maybe im not improving xd)

anyway, this dash system to me feels a bit off but i can’t point it out so hope someone can give feedback and maybe even point out the thing thats off for me.

I guess improving in scripting is just slow so i’m just gonna keep patient!
