Sure, here's an example of a simple game implemented as a single HTML file using JavaScript and pictograms:
This example creates a simple game where the player needs to run from a giant wolf. The player can speed boost by tilting the device left or right. They can also jump on zip lines and need to avoid obstacles. The game is implemented using JavaScript and utilizes the `mousemove` event to detect device tilt. The game loop continuously checks for collisions and updates the game state. If a collision with an obstacle occurs, the game ends and an alert is shown.
