Basically I would create a very simple version of a MOBA (league of legends, DOTA etc) lane. Think 1v1 ARAM in league of legends. And then create an AI to battle each other.

1 lane with a tower for the two ai players at each end, the goal is to destroy the others tower, 3 minions spawn from each tower regularly charging towards the opposing tower, they must be last hit in order gain an upgrade.

I want to keep it as simple as possible so players would be identical with 1 basic attack, upgrades are immediate upon killing creeps (increase of damage) but I realize this is still very complex.

I have about 3 months to work on this project and while I am a very quick learner I haven't done much AI before.

The basic game would be fairly easy to implement in something like gamemaker, unity or even just from scratch, possibly even limiting movement to grid based movement (potentially making running simulations much more efficient and easy). The AI part is the bit I have to learn and am worried about being too ambitious.

I'm pretty sure the basic idea is that I could set initial goals (so taking player damage is bad, doing damage to enemy player is good etc) and then I can add elements progressively (creeps, then tower) again not sure on how exactly this is implemented and dont have much of an idea of which framework to choose.

I just want to know the doable-ness of it and any suggestions would be greatly appreciated. Keep in mind even just a basic last hit minions to kill other player is good enough of a project (I think)
