Sure! Here's an example of a simple game where you can move a cube within a box using JavaScript and pictograms. The implementation is kept within a single HTML file, enclosed in script tags.
In this game, the cube is represented by a red square and can be moved within the box using the arrow keys on a smartphone. The cube cannot move outside the boundaries of the box. Adjust the `boxWidth`, `boxHeight`, `cubeWidth`, `cubeHeight`, and `stepSize` variables as per your preference for a perfect gameplay experience.
