Sure! Here's an example of a simple implementation of Flappy Bird using JavaScript and pictograms. It is enclosed in script tags within a single HTML file:
This code will create a simple Flappy Bird game where the bird is represented by the 🐦 emoji and the pipes are represented by the 🌲 emoji. The game can be played on a smartphone by tapping on the screen or by pressing the spacebar. The score is displayed at the top left corner of the canvas. When the bird collides with the pipes or goes out of bounds, the game over message will be displayed.
