Sure! Here's a simple animal version of Minecraft implemented as a single HTML file using JavaScript. Note that this is a simplified version and doesn't contain all the features of the original game.
To use this code, you'll need to replace the `emozi_himawari.png` with your own pictogram representing the animal character in the game. Additionally, you can enhance the game by adding more features such as blocks, other animals, a crafting system, and so on.
