Sure! Here's an example of a simple game about building and mining using JavaScript and pictograms. You can play it in a web browser on your smartphone:
Building and Mining Game
In this game, you have two main actions - building and mining. Clicking the "Build" button will earn you 10 resources, while clicking the "Mine" button will consume 5 resources and find 5 additional resources if you have enough. The number of resources earned is displayed below the buttons.
Note: This is a basic example and can be expanded upon to create a more complex game with additional features.
