Sure! Here's an example of a simple endless DND (Do Not Disturb) style game implemented as a single HTML file:
🧙♂️
In this game, a random player pictogram (`🧙♂️`, `🧛♀️`, `🦸♂️`, `🧟♀️`, `👽`) is displayed on the screen, representing the player character. The `updateGameScreen()` function is called every second to change the player pictogram to a new random one.
You can customize the game further by adding additional game mechanics, enemies, levels, and interactions with the player. Feel free to modify the code to suit your preferences!
