Sure! Here's an example of a simple game where you control a character and avoid obstacles using JavaScript, HTML, and pictograms. This code needs to be saved in a single HTML file:
This game uses a canvas element to render the game graphics and handles the character's movement and obstacle scrolling. The character is controlled by pressing the "ArrowUp" key on a smartphone. The game keeps track of the score, and when the character collides with an obstacle, a game over message is shown with the final score.
