Sure! Here's a simple implementation of Flappy Bird using dots as pictograms within a single HTML file:
To play the game, open the HTML file on a smartphone, and tap on the screen to make the dot (representing the bird) jump and avoid the obstacles (represented by dots as well). The goal is to pass through the gaps between the obstacles and achieve the highest score possible.
Please note that this is a basic implementation of Flappy Bird using simple dots for pictograms. You can modify and enhance the game as per your requirements and preferences.
