Sure! Here's a basic implementation of a simple Mario game using HTML, CSS, and JavaScript. You can copy and paste the code into a single HTML file and open it in a web browser to play the game. Note that this is a very basic version and can be further enhanced with graphics and additional features.
Please note that this implementation uses a placeholder image (`emozi_all/mario.png`) for Mario. You can replace it with your desired Mario image. Additionally, for a full game experience, you would need to add platforms, enemies, scorekeeping, etc. This implementation simply focuses on Mario's jumping movement.
