I think I'll try to use a behavior tree, and let the AI react to what's happening and how the player is playing. So, if you're aggressive, it can either retaliate or go on the defensive and try to hit back when able to.

It will also depend on how well I can realize my ideas :D

Thank you, I'll put it on my list :D

Not the first, but I do have a tendency to abandon and not finish stuff :)

Yes yes yes! <3
