Sure! Here's a simple cell sandbox game implemented in a single HTML file using JavaScript. The game allows you to interact with cells on a grid and simulate their behavior. Please note that this is a basic implementation, and you can enhance it further based on your requirements.
To play the game, simply open the HTML file in a web browser on your smartphone. You'll see a grid of cells that you can click to toggle their state between alive and dead. The game will simulate the behavior of the cells based on the rules of Conway's Game of Life. Cells that have live neighbors will survive, while cells without live neighbors or with too many live neighbors will die. The grid updates every 0.5 seconds to reflect the changes in cell states.
