Nyef mentioned on #lisp yesterday that there's one thing that is definitely missing and taht's the ability to have different animations for a movable, depending on the direction it is moving in.
As far as I can tell, it shouldn't require too many changes to implement (a new helper macro, a change to map-animation and some conditionalisation in ensure-animations).
Unless someone can guide me with priorities, I shall set forth on implementing this, possibly tomorrow.
