Snake Game

A pattern completion challenge where players control a snake to collect specific items while avoiding others. This game tests spatial awareness, decision-making, and precise control.

Game Mechanics

• Navigate the snake through a grid
• Collect the target food items (e.g., apples)
• Avoid the forbidden food items (e.g., bananas)
• Avoid colliding with walls, obstacles, and the snake's own body
• Collect the required number of target items to verify
