Thank you. This was initially an unintended bug but I have noticed a lot of people seem to enjoy it. In previous versions of this prototype, Gabi's slide would overwrite her momentum with a new value. However, after I implemented Movement 2.0 the slide became additive to the character's momentum.
As it so happens, Gabi's momentum is most extreme right before landing from a moving jump, as the jump carries her forward X momentum while she gains extra momentum in the Z direction from falling. If she performs a slide right as she lands back on the ground from falling, that Z momentum from falling gets accidentally redirected into the slide mechanic and will theoretically continue to add to her momentum indefinitely when performed repeatedly. I guess I didn't catch this when I wrote the movement code, but I am flattered people are enjoying this 'feature' :)
