Concept is really nice here. The little box fists are actually animated very nicely. Having some explanation on cards would be immensely helpful. Since most of the enemies have such quick attacks, the longer pre animation attacks were pretty useless. I tried to gain distance by moving away and then winding up but it was never enough. Especially since they almost always jump attack.
Overall this a great start to a turn-based-card-based-fighting game which is a neat genre that I haven't seen before!
Great job on this :)
