TouchGen: There are so many tower defense games out there, and we have covered dozens here at TouchGen. At times we still miss a gem or two, and I have to be honest that I didn’t jump out of my chair when I first heard about Kingdom Rush. The iPad version was released late in the winter of 2011, and gathered quite a lot of attention: both from critics, and players. When a iPhone version was announced it felt like a great place to start the relationship with Kingdom Rush. Tower defence games are quite perfect for the small screen in my opinion. Giving up screen estate for portability is ok for a certain type of game.
