How to Play Alien Shooter

1. Control your alien using arrow keys (or A/D) on desktop, or on-screen controls on mobile.

2. Aim and shoot at falling objects to destroy them before they reach the ground.

3. On desktop, use your mouse to aim and click to shoot. On mobile, use the "Shoot" button.

4. Each hit earns you points, and destroying an object completely gives bonus points.

5. Avoid letting objects hit your alien as this will cost you lives.

6. The game gets progressively faster and more challenging as you play.
