There is something really satisfying about just throwing hordes of disposible goons in the way of the AI. I had a good bit of fun with this.
If you added some information on how the AI moves, I think that would take the game to the next level so players can strategize more. Eventually I developed a strategy to deal with the AI (move in front and hang back until the AI moves into the attack range), but I still don't really understand it, which makes some wins and losses feel like RNG.
