Creating a fully functional Minecraft game with all the textures and items would be a complex task that cannot be accomplished within the limitations of a single HTML file. However, I can provide you with a simplified version of a Minecraft-like game implemented in JavaScript that you can play on a smartphone.
Please note that this game will not have the full features and textures of Minecraft, but it will provide a basic building and exploration experience with pictogram graphics.
To play the game, you can copy the above code into a new HTML file or open it in a browser and save it with a .html extension. The game grid will be displayed with a character represented as a gold block. You can use the arrow keys to move the character within the grid boundaries. The game grid and the character's movement are handled in JavaScript enclosed within the script tags.
Please note that this is a simplified version of Minecraft, and the implemented features are limited.
