Owner

Orbit Defender is an original twist inspired by Asteroids. Use original names, art and level designs, nothing copied from the original.

Core mechanics

Fly a ship around a small central planet in a wrap-around field. Rocks split large -> medium -> small; occasional saucer shoots back. Planet gravity gently pulls the ship.

Controls

Left/Right rotate, Up thrust, Space fire, Shift hyperspace; touch: virtual stick + fire button; gamepad stick + A/B.

Difficulty curve

More rocks per wave, faster rock velocity, saucer frequency and accuracy rise every 3 waves.

Ad reward

One extra life with a 3s shield. Limited per run by the shell's continue rules and verified by the reward server.

Art needs

Ship (+thrust frames), 3 rock sizes x 3 variants, saucer, planet, bullets, explosion particles.

Acceptance criteria

Playable in the shell through games/orbit-defender/manifest.json
Keyboard, touch and gamepad controls work
Difficulty ramps as described and is tuned for a fair first 2 minutes
Score, game over and local high scores integrated
Ad reward hook (onReward) implemented and tested with the placeholder provider
Sound effects respect mute and volume
Art assets in place (placeholder shapes acceptable until the art issue lands)
Runs at 60 fps on a mid-range phone
