Dr. Mario DX (Gameboy Color GBC)

Dr. Mario DX delivers the the classic falling-block puzzle game in FULL COLOR! You play as Dr. Mario, dropping two-colored vitamin capsules into a bottle to eliminate matching-colored viruses (red, yellow, blue) by forming lines of four or more identical colors. The gameplay is similar to Tetris but focuses on color-matching, requiring strategy to clear all viruses before the bottle fills up, with features like speed selection and a two-player mode using a Link Cable for competitive battles. 

Gameplay Mechanics:

• Objective: Clear all viruses from the playing field (a medicine bottle).
  
• Capsules: You drop two-sided capsules with combinations of red, yellow, and blue colors.
  
• Virus Colors: Viruses appear in red, yellow, and blue.
  
• Matching: Align four or more of the same color (capsule half or virus) horizontally or vertically to make them disappear.
  
• Gravity: Unsupported capsules and viruses fall down.
  
• Game Over: The game ends if capsules stack up and block the bottle's opening.
