Asteroid Blaster

A tilt-controlled asteroid shooter, ported from the AsteroidOS smartwatch game.

IDLE MODE: casual endurance blasting fun. Tilt to turn your ship in the centre of the screen; it fires on its own. Survive the waves, shoot the colour-shifting UFO for power-ups, score double inside the blue ring.

FREE FLIGHT: hunt the UFO and asteroids. Tilt sideways to turn, tilt the top edge away to thrust, back to brake. The camera follows your ship and zooms out the faster you fly, through a field twice the size of the screen. The UFO fires back.

Nine power-ups: score frenzy and shield from the start, then quad pierce, wide shot, triple shot, rapid fire, laser, chain bolt and nuke unlock as you level up. Each mode keeps its own high score.

The app asks for camera access only because that permission includes the motion sensors on SailfishOS; the camera is never used.
