1 Your ship floats in zero-gravity space — rotate left/right and thrust to move.

2 Press Space (or tap Fire) to shoot in the direction your ship is facing.

3 Large asteroids split into 2 medium, medium into 2 small, small are destroyed.

4 Clear all asteroids to advance to the next wave — each wave adds more rocks.

5 A saucer appears periodically for bonus points — watch out, it shoots back!

6 You have 3 lives. Colliding with an asteroid or saucer costs a life.

7 After losing a life you respawn with brief invincibility (ship blinks).

8 Objects wrap around the screen edges — what exits one side enters the opposite.
