This game has a surprising amount of depth that I nearly didn't experince. All of the cards can be used to combo into one another nicely, and the last level was quite challenging (beat it with 2 seconds left!!). I think a good step forward if you'd like to continue this is to consider being able to add another body/person onto the map, as once it's just down to one/2 people (whether due to samurai or exploding,) the game just turns into "how fast can I get my infect card..?"
Despite that, I still enjoyed myself. Loved the artwork and the little story between you and the queen(?) Well done :)
