Sure! Here's an example of a simple Minecraft 2D game implemented as a single HTML file using JavaScript:
This HTML code creates a 2D game environment with grass, Steve, and pigs represented by different colored squares. Steve can be controlled using touch events (on a smartphone) or arrow keys (on a computer). The objective is to move Steve to catch the randomly moving pig. Once Steve and the pig occupy the same position, an alert box notifies the player that they've won.
Please note that this is a simplified example. You can enhance the game further by adding more features like obstacles, scoring, and additional game mechanics.
