Wanting to Jump fast in 2d.

I am creating a 2d platformer in paper2d and i cant figure out how to make a character jump fast. I am very new to unreal and have done most of the tutorials.i still want him to jump high ,just a quick hop thats high enough to get over things. when i set the gravity higher he jumps slowly and falls faster. the default 2d character feels way too floaty. Thanks!
