Sure! Here's a simple game implemented as a single HTML file using JavaScript and pictograms:
This game displays a random emoji every second, and your goal is to click on it as fast as possible. The game lasts for 10 seconds, and at the end, it shows your final score.
To sell Dino emoji, you can create a separate section in the HTML file where users can purchase and display the Dino emoji. For example, you can add a button labeled "Buy Dino Emoji" that deducts the cost from the user's balance and adds the emoji to their collection.
Please note that this is just a basic implementation to give you an idea, and you can expand and customize it further according to your requirements.
