Pew Pew Land is a cartoony tower-defense game with fairly conventional gameplay but cool two-player capabilities over Bluetooth.
Fans of the tower-defense genre will quickly pick up Pew Pew Land's touch-screen interface and fast-paced tactics: you have to defeat a fixed number of enemy waves on each level, strategically placing a variety of upgradable towers (eight types in all, from simple shooters to rockets and lasers) along a fixed path with an entrance and exit. If you let too many enemies get by, the level ends. The game's help is scant but adequate, and Pew Pew Land's level design often requires trial and error to find the optimal number and type of towers to deploy (and many levels present a very narrow path to victory).
Pew Pew Land's graphics and sound aren't remarkable, its difficulty can be inconsistent, and it lacks some features that are standard on other TD games (like variable speed control). If you want to play with a friend, though, Pew Pew Land has a fun multiplayer mode that lets you simultaneously split a single map with another player over Bluetooth.
