This game is pretty fun (I played it for 2 hours straight after downloading) I'm not 100% sure how the fighting mechanics work though. Sometimes just button smashing seems to work better than tactics (might just be me).
Some ideas: a training mode (to help people understands the mechanics) and maybe having an option for changing the speed of the enemies (so you can see what they are about to do)
I'd give this a 9/10
