Nice Game! Had some difficulty at first with all the battles after (and including) Guy the Great, but got used to them. Most of the time I still ended up moving in a square formation to constantly revive the one person that got hit, not sure if it's the intended way but it is the only way that worked for me.
One complaint I have is the size of the UI and UI font. I would find the game more enjoyable if I didn't have to strain my eyes so much. Perhaps an option for the UI size (1, 1.5, 2)? just make sure to keep the scale ;)
