There's quite a lot of submissions with the same idea as this one, but unfortunately I think it is very rarely fun. So far as I can tell, there's no strategy that can make you work well with the AI control (actually, the AI control just seems to be random movement inputs). For me at least, I am just trying to play the game in the gaps where it is actually playable.
This is a shame because the art style is neat and I think I would have had a lot of fun with the combat system if not for the constant interruptions!
