Asteroid-Dodger is a thrilling survival game for AsteroidOS where you tilt your watch to surf through an ever-denser asteroid field, nailing near-miss combos for big points. Master the art of close dodges, grab power-up potions to shift the odds, and climb four difficulty tiers from relaxed to ruthless. With retro arcade flair, a shader death sequence, and accelerometer-driven action, this game turns your wrist into a playground of skill and reflexes.
- Cadet Swerver — Relaxed density and speed. The original game feel.
- Captain Slipstreamer — Faster scroll, tighter asteroid density.
- Commander Stardust — Reduced power-up window, rarer invincibility.
- Major Roadkill — No invincibility pickup. Godspeed.
Your last-played difficulty is remembered. A per-difficulty leaderboard on the game over screen tracks your best score and max level across all four tiers.
- Random generation of the asteroid field and power-ups for endless variety.
- Combo system: Near-miss dodging within a 2-second window chains into multiplied points. A green meter below the score shows the combo window.
- Level progression: Every 100 asteroids survived increases speed and density.
- Shield system: Start with 2 shields, collect blue power-ups to rebuild up to 10.
- Highscore tracking: Stored per difficulty in
~/.config/asteroid-dodger/game.ini.
- Death shader: A fatal hit decelerates the field and plays an expanding ring shader over the player before the game over screen appears.
- Background flashes: Color-coded atmospheric flashes signal game events.
- Parallax effect: Slower non-colliding large asteroids add depth.
- Particle effects: Score particles grow larger and turn pink at high combo values.
- Hit feedback: Player blinks during the 2-second grace invincibility window.
- Haptic feedback: Vibration on damage and level advancement.
- Combo area visualization: Diamond overlay shows the near-miss detection zone.
- Dynamic power-up bars: Each active power-up shows a color-coded duration bar.
- Blue: Gain +1 shield point (up to 10).
- Pink: 10 seconds of invincibility. Stacks with grace period — not available on Major Roadkill.
- Yellow: 6-second speed boost with unpredictable "drunk" steering.
- Green: 2× score multiplier for 10 seconds.
- Cyan: 6-second slow-motion — halves scroll speed and spawn rate.
- Orange: Shrink to 50% size, growing back over 6 seconds.
- Purple: Auto-fire — 30 shots over 6 seconds destroy asteroids and potions.
- Red: Laser swipe — sweeps the screen clear of all objects.
- Tilt to move: Accelerometer controls horizontal player position.
- Start screen: Select difficulty via tap-cycling ValueCycler, then tap Die Now.
- Calibration: 2-second hold to set your comfortable neutral tilt position.
- Pause: Tap anywhere during play to pause. Tap again to resume.
- Game over screen: Shows current run result and full per-difficulty leaderboard.
- Die Again: Instantly restarts at current difficulty — no re-calibration needed.
- Exact crash detection:
QtShapeshitbox shaped like the AsteroidOS logo. - Debug tools: FPS counter and graph toggle accessible from the pause screen.
- Combo chains require consecutive near-misses within 2 seconds. Collecting any power-up resets the combo window — weigh the trade-off at high counts.
- Destroying asteroids with auto-fire or laser swipe removes them from the level progression count, letting you delay the speed and density ramp.
- Grace period and pink invincibility stack — taking a hit while pink is active keeps you protected for both durations.
