Coding montage! I've added some rules, that might make the debugging more efficient. Jumping has been made similar to what Teeworlds has, as well as "air backforce" function, which will slow the character down, if you go below the air slowing point, which in case this is 512. Next is gonna be running / dashing with a more appropriate environment.
