Script

Sure! Here's a sample space game implemented as a single HTML file using JavaScript. The game is played on a smartphone and includes some pictograms for a visual experience. Simply copy the code below and save it as an HTML file to play the game.

Score: 0

This game is a simple space game where the player controls a spaceship using the left and right arrow keys on their smartphone. The objective is to avoid the asteroids (represented by 🌑) falling from the top of the screen while collecting stars (represented by ⭐) for points. The game ends if the spaceship collides with an asteroid. Note: The game loop here is implemented using `setInterval` to continuously create asteroids and move them down the screen. For more complex games, it's recommended to use more advanced game development frameworks like Phaser or PixiJS.
