Sure, here's an example of an HTML file that implements a simple "Escape the Backrooms" game using JavaScript and pictograms:
Escape the Backrooms!
🚶
In this game, you control a player character represented by a walking symbol (
🚶) and need to navigate through walls by using arrow keys. The goal is to reach the green "exit" block at the bottom right corner of the screen. When you reach the exit, a congrats message is displayed.
Note: This is a simple implementation and can be further enhanced with additional features, levels, and graphics.
