Everyone remembers Dr. Mario as that amazing puzzle game that came out shortly after Tetris, and no worries because it still is amazing. Lately I have been getting back into retro games and this was an obvious pick up for my 89 Game Boy. I love the game and it is everything that I remember but... the Game Boy version was way harder than the NES version or any other version I remember. The pills come down wicked fast on the higher levels and settings. I would only pick this version of the game up if you really want to have that retro experience on your classic Game Boy.
