Sure! Here's a simple game implemented as a single HTML file that can be played on a smartphone using pictograms:
Galaxy 2024
🚀
🌌
👽
🛸
🌠
In this game, pictograms representing different elements related to space and galaxy are displayed on the screen. When clicked, each pictogram becomes active and is highlighted. Only one pictogram can be active at a time, as denoted by the `active` class. This simple game allows the player to interact with the pictograms on their smartphone.
Feel free to customize and enhance the game further based on your specific requirements.
