Sure, here's an example of a simple game where you have to move around a spider without getting caught. The game is implemented as a single HTML file using JavaScript:
In this game, you play as a player represented by a blue square ("pictogram"). Your goal is to move around and collect three keys before reaching the green door to escape. However, you must avoid getting caught by the red spider.
You can control the player's movement using the arrow keys on your smartphone or by tapping on the player element. If you get caught by the spider, a game over message will be displayed, and if you collect all three keys and reach the door, a congratulations message will be shown.
Please note that this is a basic example and can be further enhanced with additional features, levels, and graphics.
