Sure! Here's an example of a simple game in a single HTML file that displays a cube and allows the user to rotate it using cross buttons:
In this game, a 3D cube is displayed using CSS properties to make it appear three-dimensional. The cube can be rotated along the X and Y axes by clicking on the cross buttons (`⇧` and `⇨`). When a button is clicked, the cube is rotated accordingly.
Please note that since you specifically mentioned using pictograms, I've used arrow symbols as buttons. You can change them to pictograms of your choice.
