Sure, here's an example implementation of a simple space shooter game like Galaga using JavaScript, HTML, and pictograms. Please note that the following code snippet is a simplified version and may require further enhancements to make it a complete and polished game.
To use this code, you would need to replace `"emozi_rabbit.png"` with the actual path to the player ship image file, and `"emozi_all/player.png"` with the actual path to the bullet image file. You can also further customize and improve the game logic, add sound effects, enemy ship movement patterns, collision detection, and more.
Note: This is a basic implementation provided for demonstration purposes only. A complete and polished game would require additional development and refinements.
