Asteroids

Just a bit of fun — the result of experimenting with Java applets for the first time. The original was a Java applet, which no browser will run anymore, so it's been rebuilt from scratch in HTML5 canvas, with its original gimmick intact: you get all your lives at once. They fly together as a squadron — point them with the mouse, the left button fires, the right button thrusts. The aliens are a little more deadly, which means more points, and more points mean more ships: one more joins the fleet every 10,000.

Aim with the mouse, left-click fires, right-click thrusts — or arrows to rotate, ↑ thrust, SPACE fire, or the buttons on a phone. Rocks split when you hit them; the red saucer is worth 200. One more ship joins the fleet every 10,000.

• Big rock 20 pts · medium 50 · small 100 · saucer 200
• Everything wraps around the screen edges
• Your whole fleet flies as one — lose a ship and the rest fight on (game over when the last one goes)
• Survivors get a few seconds of invulnerability when one is lost or a level begins (they blink)
• Clear all the rocks to advance a level — each one's a little busier
