Sure! Here's a sample implementation of the game using JavaScript and HTML:
Score: 0
To use this code, you need to have image files named `forest.jpg`, `emozi_all/forest.png`, `emozi_cat.png`, `emozi_rabbit.png`, and some zombie images (you can name them as `emozi_all/zombie.png`, `emozi_bear.png`, etc.) in the same directory as the HTML file.
In this game, you can tap on the gun icons in the inventory to select the desired weapon. Then, by tapping on the game area (forest), you shoot the selected weapon at the zombies. Each successful hit increases your score. The game keeps track of the score and displays it on the screen.
Please note that this is a basic example, and you can further enhance and customize it as per your requirements.
