I first released the game in 2010. There was originally only one small area to run around in, and it was running off my DSL line, so it could only support 5-10 players. Also, the client was only available as a Java applet. Websockets made it possible to create a Javascript client. There is also a mobile version available which includes controls for touch.

Comments from other people trying out the game are hilarious:
