On the topic of jumping:
jumpForce has been set to 840 which is more than enough to clear a three brick high fence.
jumpDelay has been set to 30 to hinder a player's ability to climb walls.
I am working on a way to cripple the ridiculous jump/crouch style of fighting. Right now I have a solution, but there is a bug with crouching under objects. When I fix this single bug, we'll test it and see what kind of experience combat brings. The bug has been fixed and the solution is working optimally. Jumping while crouched is no longer possible and crouching while mid-air does not benefit you during combat.
