This is Dr. Mario for the 8-bit Nintendo Entertainment System. Dr. Mario is a puzzle game released on the NES in 1990. The goal of the game is simple, rid each level of Blue, Red, and Yellow viruses. You accomplish this task by rotating vitamins and lining up colors. Overall, Dr. Mario is an awesome puzzle game and one of my all time favorites in the genre. I love the simple game play mechanics, the simplistic, yet charming graphics, and the awesome 8-bit music.
