Hello, I understand. You're right that the way should be more or less like the new animated cgs. I don't think this would take too much to implement, so probably I will update it this week with two new features: Animated backgrounds (load background as spritesheet and it will loop forever), and background cgs (exactly the same as cgs, but will be loaded behind the characters). The second feature will be interesting in cases like when you have an actual static background but a few animated parts (like a torch with moving fire, for example).
Anyways, I'll post in this thread when it is done.
Cheers!
