TeamXbox writes: "Sometimes, the simplest game designs are the most fun. Look at Space Invaders. Look at Tetris. Look at Braid. They're all really easy to play, with only a couple of controls to deal with, but there's a load of challenge that comes from the gameplay within that basic framework.
The same can be said for Droplitz, an Xbox Live Arcade puzzle game from Atlus. And know that there's a lot of challenge in this interesting and compelling game."
