Build a fixed-screen, mouse-controlled arcade target shooter inspired by the classic Duck Hunt formula. Use original or placeholder visuals and sounds only. Do not copy Nintendo art, audio, names, or characters. The important goal is to reproduce the minute-to-minute mechanics: targets appear, the player has three shots, hit or miss feedback happens immediately, ten targets make a round, and the player advances only if they meet the round's hit requirement.
- Implement a fixed-screen 2D shooting gallery game controlled primarily with the mouse.
- Use an internal playfield coordinate system of
800 x 600pixels, scaling the canvas to fit the window while preserving aspect ratio. - Render a simple background with sky, ground/grass, and a visible play area; placeholder shapes are acceptable.
- Do not implement scrolling, player movement, first-person camera movement, projectile travel, or weapon swapping.
