Sure! Here's a simple game implemented as a single HTML file using JavaScript. Please note that this is a basic implementation and can be enhanced further.
To use this game, create an HTML file and paste the above code into it. Save any suitable image for `emozi_all/game.png` and `emozi_all/zombie.png` in the same directory as the HTML file. Customize the `emozi_bear.png` and `emozi_all/zombie.png` images as desired to match the game theme.
When you open the HTML file in a web browser, you can play the game using the L key on your keyboard. Killing a zombie will increase your score until you reach a score of 100, at which point you win the game.
