Sure! Here's an example of a simple game called "The Jumper" implemented in a single HTML file using JavaScript and pictograms:
The Jumper
Tap/click anywhere to make the jumper jump!
This game consists of a simple canvas where a jumper is represented by a blue circle. When the user taps or clicks anywhere on the canvas, the jumper will jump upwards. Gravity will then bring the jumper back down. The game loop continuously updates the game state and renders the jumper on the canvas.
