Sure! Here's an example of a game called "Animal Lab" implemented as a single HTML file with JavaScript. The game allows players to mix different animals together to create new hybrid animals.
Please note that you need to replace `lab_background.jpg`, `emozi_all/background.png`, `emozi_apple.png`, and `emozi_bear.png` with actual image files for the lab background and animal pictograms. Also, feel free to extend the `animalImages` object with more animal images as per your game requirements.
