Breakout 480x320 is a free Breakout game for 480x320 devices. The gameplay is simple, just keep the ball in the field with your paddle, and make sure these blocks disappear. While there are still lots of features to implement before the final version appears, this game already offers a solid gameplay and a stable graphics engine. Just tap the screen to start a game, control the paddle either via the stylus or 5way and make sure you don't loose that ball, because it's the only one you've got. This is still beta software, so if you don't want to test prerelease software, stay away!
