Sure, here's a simple text-based game inspired by Minecraft that you can play as a finished game. It is implemented as a single HTML file enclosed in script tags. Please note that this is a text-only game and does not use pictograms.
To play the game, simply copy and paste the above code into a new HTML file and open it in your smartphone's web browser. You can use the arrow keys on your smartphone's keyboard to move the player (`👤`) around the grid and explore the game world represented by empty cells (`⬜`). Have fun!
