Dr. Mario

The Good
This game has all the wonderful puzzle-solving and level-clearing action that the original Tetris had, and this is a quick addiction, so whenever you find a brief moment you will want to play this game. And the gameplay is so complicated, yet so simplistic, because it's just dropping colors onto colors (rather shades of gray) and yet it will take many weeks to master the science of pulling off combinations.

The Bad
The later levels (starting with Level 13 and going through 20) are practically impossible to beat, and it would be wise to just not attempt them. Also, the music grates on you, and playing this game for extended periods will cause your dreams to be full of that psycho MIDI and dropping pills onto bacteria.

The Bottom Line
This game is a Tetris clone modified by Nintendo to cater to a younger audience and with a Mario theme thrown in. This game has absolutely nothing to do with Mario or his compadres, but is one of those simple chain-reaction puzzlers that will have you clearing blocks in your mind far after your Game Boy has been shut off.
