flemmig : You probably put the folder on the "plugins". It should be in the "behaviors" folder ;)
lunarray : This is amazing work! Perfect for my needs, and it's good to know we'll be having a more optimized and bug-free code! Seriously, this should be included in the official C2 bundle. And you should name it just Tween, as it isn't "lite" at all :D
BTW, I'm getting an error if I try to use the "create/initialize" action:
Uncaught reference error: tweened is not defined (on line 432)
