This is a great model, thanks! I wonder, could you give some information as to how the animations should be used in-game. Like how to chain them together, etc.

Most of them are straight forward enough:

"speed up" play when character is starting to run.

"slow down" for when the character stops running.

"fall (run)" for transitioning between running and falling.

"fall (air)" for after fall (run) and while falling.

"fall (ground)" ? I don't know.

Everything else is pretty self explanatory, but what's the ground/landing part of the fall sequence?
