Sure! Here's an example of a simple jumping game where you play as a character named Maro and try to eliminate Goombas. The game will be implemented as a single HTML file with JavaScript code enclosed in script tags:
In this game, you control Maro using the spacebar to jump over the Goombas. The goal is to avoid colliding with the Goombas and score as many points as possible. The game starts automatically when the page loads, and the score is displayed at the top left corner of the canvas. If Maro collides with a Goomba, the game ends, and the "Game Over!" message is displayed on the screen.
Please note that you need to replace the `emozi_all/pictogram.png` and `emozi_all/pictogram.png` with actual pictogram images of Maro and Goombas for the game to work properly.
