Great game engine!
I would definitely be willing to help you with the continuation of this. I've made a couple of other game replicas, including a Final Fantasy game engine. The engine looks great so far, except for the high amount of tweening which slows down the game, which I have some ideas for. Go ahead and e-mail amps2003@hotmail.com or InstantMessage MaximumAmps on AIM to contact me!
Keep up the good work!
