Let me think through this systematically:\n\n1. First, I need to plan the game structure:\n - HTML structure with canvas for the game\n - CSS for styling and layout\n - JavaScript for game logic\n\n2. Core game components I need:\n - Bird class with physics (velocity, gravity, collision)\n - Pig class as targets\n - Block class for obstacles\n - Slingshot mechanics for aiming and launching\n - Scoring system\n - Win/lose conditions\n\n3. Game mechanics to implement:\n - Mouse interaction for aiming and launching\n - Physics simulation with gravity and friction\n - Collision detection between birds, pigs, and blocks\n - Trail effect for bird movement\n - Game state management\n\n4. Visual elements:\n - Colorful background with sky and ground\n - Animated bird with eyes and beak\n - Green pigs with faces\n - Brown wooden blocks\n - Slingshot with rubber band visualization\n\n5. User interface:\n - Score display\n - Birds remaining counter\n - Instructions for the player\n - Win/lose screen\n\nLet me implement this step by step, creating a fully functional game with proper physics, graphics, and user interaction."}]} |
