This game either works using one computer (if you press the one computer), or with two computers (or two instances of the program running on one computer). For two player, make sure you set up meshing, and connect one instance of the program running as host, and use the IP address to connect to the mesh with the other instance of the program running. Make sure the sound is up, in case you get a tie, or scratch. I think you'll like the indicator. Have fun.
