Sure! Here's a simple cat merging game implemented in a single HTML file using JavaScript. You can play it on a smartphone:
Cat Merging Game
Drag and drop the cats to merge them!
To play the game, you can save the above code as a `.html` file and open it in a web browser on your smartphone. The game allows you to drag and drop the two cat images (`cat1` and `cat2`) into the `mergedCat` container. Once dropped, the `mergedCat` container will display the merged cat image.
Please note that the game assumes you have two cat images (`emozi_all/game.png` and `emozi_all/cat.png`) in the same directory as the HTML file. Feel free to replace those image names with your own cat images or modify the code as needed to suit your requirements.
