Sure! Here's a simple text-based version of a Minecraft game that you can play on a smartphone. The game presents a grid of blocks and allows the player to move around and dig or build blocks.
To play the game:
- Open any text editor and copy the above code into a new file with an `.html` extension.
- Save the file.
- Open the saved file on your smartphone using any web browser.
- Use the arrow keys or the keys 'w', 'a', 's', 'd' to move the player around.
- Press the spacebar to dig or build blocks.
Note that this is a very basic version of the Minecraft game, and does not include all the features and mechanics of the actual game.
