Unfortunately they're made with the DroidScript image canvas so that they're very slow. I also had less knowledge when I made them as today. I'd change a lot when looking at the code today. But RPGDemo can be extended.
The second point is that I don't have enough time to start another big project. I still have to do some schoolwork from time to time.
But I believe Netpower is currently working on an RPG library. I dont know what he has planned with it - but you can ask him :)
Best regards,
