Sure! Here's an example of a simple diving game implemented in a single HTML file with JavaScript. Please note that this is a basic implementation and can be further enhanced with your desired features and graphics:
Diving Game
Score: 0
To use this code, please make sure to replace the `emozi_rabbit.png` and `emozi_apple.png` with the actual pictograms or images you want to use for the diver and splash animations.
Once the game is loaded in a smartphone's browser, the player can use the left and right arrow keys to move the diver and avoid the falling obstacles. The score increases with each successfully avoided obstacle, and it will display "Game Over" with the final score when the diver collides with an obstacle.
Note: The functionality and appearance can be further improved based on your requirements and preferences. This is just a basic implementation to get you started with a diving game concept.
