A nice defense type game, once you get abominations they seem pretty strong with their "Vampirism" powers, though they can only handle so many enemies. I lasted til Wave 4, it's simple fun for what you have. I feel like the UI could have been made a little better since going up and down frantically to see what resources you have available clearly took up some time, it would also have been fun if you were able to place your units strategically. But, it was fun for the time I played it!
