It's not that the engine itself it a bad engine, it's just there is every where to improve (Btw, Ima start ranting on right about here)
This "engine" has some cool effects, it allows you do kill an enemy using three different attacks and allows the enemy to fight back, but it lacks on nearly everything else.
-Allow character to know when to stop hitting the enemy (when it's already dead and it's health is just going down)
-Make the enemy A.I more smooth, (way to laggy)
-Stop making so many new topics....
-You should hardly ever (unless you started flash a week ago) be impressed w/ something like this.
-Allow air attacks
-Better Enemy A.I would be nice
-Allow a certain part of the enemy be different than the other enemy so you don't feel like your fighting the same enemy (even though you really are.)
Thats just my 2 cents, anything else?
