This is a combination real-time tower defense game and deckbuilding game. You use cards to earn money and pay for buildings and critters, which then defend against the waves of monsters that approach from either left or right. 6 different rat clans that all have different and neat approaches. I enjoyed this game but I am not good enough at the real-time aspect and it ends up making me nervous. They smartly slow time when you zoom in on a card, but it's not enough. Watching high level play I notice constant pausing and unpausing, which would drive me nuts. So...neat approach, lots of fun touches in the game that draw you in, but ultimately not for me.
