Instead, Andriasang describes the WiiWare game as a unique variation of tower defense. As heroes storm your tower, you delay their progress by adding floors to the structure and filling them with monsters. The strategy comes not only from managing your resources enough to build as many floors as you can, but also in placing things so that there isn't too much stuff on one floor. If there is, the heroes can just skip over a floor!
