« I guess it's okish overall but as an avid card game player I found myself almost immediately bored. Cards and their effects feel meh and the mechanic of dodging left and right just does not feel compelling to me. »

« Fun at first and then gets repetitive quickly. It is not a rouge-LITE, so there are no permanent upgrades to work for. So you are just doing the same thing over and over and hoping to win to tease out five sentences of story at the end. »
