A bit too simple
Dr. Mario is a fine puzzle game and Tetris clone. The main problem is that it doesn't keep your interest up well enough. After you have cleared the first couple of top rows of viruses, which can be quite stressful and requires total focus on higher levels, the game lapses in to an arbitrary state where you clean up the bottom half of the screen without the need of any real effort. With an addition of more combos this part of the game might have snared my interest more.Pros & Cons
+ Good Tetris clone- Part of the gameplay feels like a chore
