Sure! Here's a sample code for the game you described:
Explanation:
This code creates a simple game where the player needs to leave the game within a certain time limit. After waiting for 3 seconds, the game starts and displays messages asking the player to leave. After 3 more seconds, a cat image starts running across the screen, getting faster as time passes. If the cat runs off the screen before the player leaves the game, it's game over.
Note: Make sure to replace `"emozi_all/cat.png"` with the actual path to your cat image file.
To play the game, simply save the code as an HTML file and open it in a web browser on your smartphone.
