Sure, here's an example of a simple game implemented as a single HTML file using JavaScript. Please note that this is a basic example and may not include all the features you described. You can enhance and customize it further based on your requirements.
To use this code, you need to create two image files: "emozi_rabbit.png" and "emozi_apple.png", which should contain the pictograms for the characters. Place these image files in the same directory as the HTML file. The game will start when you open the HTML file in a web browser. Use arrow keys to move the character and avoid colliding with the glitch. The game ends when a collision occurs, displaying a "Game Over!" message.
Feel free to modify and expand on this example to create a fully-fledged game with additional features according to your requirements.
