It's good. It's a dinky vertical RPG. Art style reminds me a little of Darkest Dungeon. Attacks are card based, the draw is random, mana restricts how many Attack based cards you can select on a turn.
Build up your squad, enhance units, create a unique squad of adventurers each bringing a set of skills that makes the squad all the more deadlier. In action this is easy to sort and it's fun to tinker with your line up.
I quite liked the tutorial. Easy to get into. It appears to be suited towards casual players, pick up put down anytime you like, that sort of playability. As such this appeals. I'm going to give it another week before updating my review.
