Sure! Here's an example of a simple text-based game called "Among Tasks" that follows your requirements:
This is a basic template for the game, which you can expand upon to add interactive elements and improve the user experience. The game mechanics and flow are implemented using JavaScript. You can uncomment the `showTasks()`, `doTask()`, `reportDeadBody()`, `emergencyMeeting()`, and `kill()` commands to simulate gameplay and test the functionalities of the game.
Please note that this code is a simplified example and may require additional work to create a fully functional game with graphics, mobile-friendly UI, and multiplayer functionality, which could be beyond the scope of a single HTML file.
