It's an interesting take on a war game - turn-based battles. It's a bit like a JRPG or a turn-based strategy game, but without the wandering-around part. The first level is easy, but from the second onward you have to better think of the tactic in regards to healing and shielding. The attack can always fail, so it's never predictable.
