wraking my brain here

So I decided to rework the physics engine for the magic 8 ball girl adventure game from scratch, which widdled down to rewriting the way the jumping and falling worked so that it fit into an exact grid and I didn't have any more risk of falling through the floor.

Worked so far, but the jumping lacked that nice gradual feel to it. So I'm currently working out a script that would make the height of the jump gradually decrease until they started falling.
I'm overthinking a lot of it, and there're probably some in depth tutorials on it, but I've got a stubborn streak when it comes to stuff like this.
