The title is self explanatory.
Double jump immediately after jumping, then double jump after you start falling down
Double jump height is the same in both cases
It’s much shorter while falling
Also I wanted to mention, if this is fixed, the short jump is actually kind of useful sometimes (especially on Hinderance), it just feels kind of awkward to use since the same button can perform both high and low jumps. Might be nice if the short hop was assigned to the crouch/slide button while midair or something.
