Would be nice to have something to do during battles. Just watching is boring, considering that outside battles half the time you're watching, too... Consider adding spells, abilities, stance change for each unit (defensive/agile/offensive...) and/or in-battle orders in the next game.
The concept is good, really, but a game needs to be a game... and this one seems like I'm watching some other person playing.
I started at level 31 or 32. Haver over 2 million HP after a couple level ups and the game is extremely easy. I hope it's a bug because if not I don't understand the purpose.
