Just download, unzip and run to play.

The game is designed to be played with multiple people, but can be played alone if the host starts a game by themselves. 

This game is intended to be played primarily on a single screen, so the host will need some sort of video-conferencing software with a "Share Screen" feature in order to play it with others.

The current limit on players in a single game is 20, but I believe the design could also be scaled up to work with even larger crowds.
