Sure! Here's an example of a simple sandbox game that allows you to make and customize different items using pictograms. It's implemented as a single HTML file with enclosed JavaScript code within script tags.
Sandbox Game - Make and Customize Items
To play the game, open the HTML file in a web browser (preferably on a smartphone for the best experience). The canvas represents the sandbox where you can create and customize items.
Simply click on the canvas to create a new item. A prompt will ask you for the name of the item (choose from tree, house, car, flower, or rocket). The selected item will be placed at the location you clicked on the canvas, displayed as a corresponding pictogram.
Feel free to customize the itemOptions object with more items and pictograms as desired.
