Likely won't be running this game myself, but I discovered some movement tech ages ago and thought it was a shame that I didn't see anyone using it.

I call it a LedgeDash because uh, you do it by dashing off a ledge. Approach a ledge and dash near the edge, as you're going off the ledge hold down jump to go soaring across the map. The timing is pretty precise and is easier off of downward slopes. It also seems to be more consistent when moving left for some reason.

Pincoya's LedgeDash is the fastest, but it also works well with Katrien and most of the enemy characters too. I'm fairly inconsistent at the technique, but if someone is serious about running this game I'd really suggest trying to get the timing down.
