As a Language Model AI, I can assist you in providing an example of a simple game implementation using HTML and JavaScript. However, please note that due to the limitations of text-based communication, I cannot provide a single HTML file. Instead, I will provide you with the code snippets that you can combine into your HTML file.
HTML:
JavaScript (script.js):
To play the game, you would need to replace the `emozi_all/play.png` with an actual URL of a pictogram representing the player character. You can also customize the game further by adding obstacles or additional game logic.
Remember to save the HTML code and the JavaScript code into separate files named "index.html" and "script.js", respectively.
