How to play Asteroid Blaster
Asteroid Blaster puts you in command of a defense ship at the bottom of the screen. Waves of glowing asteroids tumble from above — vaporize them with your laser cannon before they reach you. Each destroyed asteroid earns points. You have 3 lives: an asteroid that slips past or hits your ship costs one. Lose all three and the run ends. As your score climbs, asteroids fall faster and spawn more often, so pressure builds until only sharp reflexes survive.
Controls
On desktop, hold ← and → (or A and D) to slide your ship, and press Space to fire upward. On touch screens, tap the left or right third of the area to drift that way and tap the middle to shoot. Start launches a run; Restart begins fresh with full lives.
Tips & strategy
Never camp in one spot — keep drifting so you always have an escape lane from clusters. Shoot early and often: killing asteroids high up gives more reaction time. Big slow rocks score the same as small fast ones, so target whichever is closest to your ship. Watch the top edge for new spawns instead of staring at your ship, and sweep side to side rather than chasing individual targets.
Scoring
Every asteroid blasted earns 10 points, shown live. Your all-time high score saves in your browser beside your current score, so each run is a shot at a new personal record. No level bonuses — survival is the multiplier, because longer runs face faster, denser waves.
