Sure! Here's a simple text-based manager game implemented as a single HTML file using JavaScript:
In this game, you start with $1000, 1 employee, and level 1. You can perform various actions such as hiring employees, promoting employees, training employees, or quitting the game. Each action has a cost associated with it, and your money will decrease accordingly. The game will continue until you choose to quit.
Note: Since this is a simple text-based game, pictograms are not included. However, you can enhance the visual representation by modifying the HTML and CSS part to include relevant pictograms or images.
