Air Drill oddity

There's something funny about how the Air Drill ability's horizontal speed is calculated, because if your character's normalspeed is low enough, it'll actually send you backwards. Setting normalspeed to 25 seems to be an equilibrium point at which you'll fly straight up.

EDIT: Actually, it looks like characters with different actionspd values have different equilibrium points. Puffball X, for example, has his somewhere between 6 and 7. Nevertheless, there's always some normalspeed/actionspd value combinations that result in a character going backwards, and that's just weird.

That might actually be useful, but yet again that does sound weird.
