Query: Horrible Game for Overrated System

This game is basically a joke. It's a puzzle game that's like Tetris, only much less fun. Back in the GameBoy era this might have been a good title, but today it's just can't keep up. Graphics and sound are amazingly bad, but much of that is the fault of the PSP, not just the game. PSP is very underpowered. Also the battery life on the PSP when playing this game is just terrible, you practically have to play right next to a power outlet.Some people are using this game to illegally downgrade their firmware. I personally know two people who bricked their PSPs trying to do this so I suggest you do not attempt this. Just stay away from this awful game and the joke of a console that is the PSP.
