Sure, here is a simple game implementation that allows you to mine, build, and craft in a 3D environment using pictograms. Please note that this is just a basic example and may require further development to fully meet your requirements.
In this game, you can control the player using the arrow keys on your smartphone. Pressing the 'm' key will mine resources, and pressing the 'c' key will craft items. The resources count is displayed on the top left corner of the screen.
