Roogoo has a simple premise. Play Tetris and amplify the difficulty to ten. You are a tasked with saving the planet Roo by dropping "meteors" to the bottom of the stage. It is a simple concept, but the later levels get insanely difficult. That almost set me away, yet I(the reviewer) always came back for one more round.
It was shocking how well each background looked. The start of the game you are in clouds surrounded by floating platforms. The more you progress a darker tone is seen as you travel to the center of Roo. The game is full of color so it is very difficult to get bored playing this game. The game also supports high-definition graphics which of course only improve the game.
