Sure! Here's an example of a simple 3D game that takes place in a forest using HTML, JavaScript, and pictograms. Save the code below in a file named "forest_game.html" and open it in a web browser:
In this game, you will see a forest represented by a gray game container. By clicking anywhere inside the container, a player (represented by a yellow square pictogram) will move to that location. If the player collides with any trees (represented by a tree pictogram), an alert message will appear.
Please note that you need to replace the `url('emozi_all/tree.png')` with the actual URL of the tree pictogram you want to use. Make sure to update the URL in the `background` CSS property of the `.tree` class.
