Why is there a freakin' Jump button?
 

There is no platform part of the game. (please tell me you know what that meant)

I use Jump for doing a 360 in the air, this is only for celebrating, like winning a KQ.

That is why.

Its the biggest key on your keyboard (space) ^^ It serves no purpose just hopping acouple feet into the air.

I feel incomplete if I don't have the ability to jump or go long periods of running.

I use it to look funny in the air when getting hit when mobbing :3

it saves u from having to look for the "happy" emotion XD (for girls anyway.. we do the jump with joy sort of thing with the "happy" emotion)

It allows you to experience free fall for two seconds when jumping while moving down a large flight of stairs.

the game uses a 2-D Coordination System. So they cant implement jumping correctly. But because jumping is something the player really want to do, it was implemented by using a animation.

In short u can only jump to a a place u can walk to.

it's just for the style :)
imagine if we had to jump over sumthing, that would be weird. and hard sumtimes, well it could make fiesta better but same time it could get fuked.
