Galaxian is a classic arcade game developed by Namco. The objective of the game is to destroy enemy spacecraft and score as many points as possible.

Here's how to play Galaxian:

1. Start the game: Insert a coin or press the start button to begin playing.

2. Navigate your spacecraft: Use the arrow keys to navigate your spacecraft across the screen. You can move left and right, but cannot move up and down.

3. Shoot the enemy spacecraft: Press the spacebar to shoot missiles at the enemy spacecraft. Destroy as many enemies as possible to earn points.

4. Avoid enemy fire: The enemy spacecraft will also shoot at you, so avoid their fire to stay alive.

5. Collect bonuses: Occasionally, bonus items will appear on the screen. Collect these items to earn extra points.

6. Progress through the levels: The game consists of multiple levels, each with its own set of challenges. Progress through the levels by destroying all enemy spacecraft and earning as many points as possible.

In Galaxian, points are earned by destroying enemy spacecraft and collecting bonus items. The more enemies you destroy and bonuses you collect, the higher your score will be. To progress through the levels, you must destroy all enemy spacecraft in each level.
