so, I've noticed something about the enemy's in this game, namely, they like to pick one character, and just focus them, and it's kinda... I don't think "lame" is the right word for it, but it makes it easy. But also ironically stupid hard to fail.
If that were tweaked a bit in the enemy AI it'd feel a bit better in battles. Slightly more challenging, and make failure a real threat at most times.
Outside of that, I can see this game having some real potential! and I cant wait to see what comes next!
Hmmm, have you tried looking for a different AI script then? or do you think that editing the current one would be an easier method to try then? (or maybe there's an additional plugin that would work with it?)
honestly, with how it looks like you're trying to make it work, it may need to be more custom made. Though there's a few games that seems to have something similar to what you're trying to do; one's called "Mira Co rescue" and the other is called "Lustfall" Maybe try asking those dev's for some help if they're up to it. Though they do seem busy at the moment, and that's just an idea. It's up to you what to do.
Still, I hope that you have a good day, Christmas, new year, or heck, a good year for the whole of next year, I do really like this demo. Lot's of potential in this game right here.
See ya' at the next update! I'm sure you'll do good no matter what ya do! ^w^
