Sure! Here's an example of a simple bird game implemented as a single HTML file using JavaScript. It can be played on a smartphone and includes pictograms for visuals.
Score: 0
In this bird game, you control the bird by tapping on the screen (click event). The objective is to avoid the green obstacles by flying over them. Each time you pass an obstacle, your score increases by 1. If the bird collides with an obstacle, the game ends, and the score is reset.
Note: The game assumes you have an image named "emozi_all/game.png" stored in the same directory as the HTML file. Feel free to replace it with your own bird pictogram/image.
