Because many Users ask me on E-Mail, if this support on mobile devices: YES, the Client work on Android/iOS and the Server is running on Windows. BUT there are not mobiles support like virtual button/virtual joystick. I'll add them later on Update or you build own virtual key. :)
Hule Ball - created by Physics Box2D - is a multiplayer top-down-football/air-hockey game. You can play it together with your friends. The main objective of the game? Try to get the ball into the enemy goal.
And the best - this is a Engine! You'll get the source of Hule Ball! So you can build your own Hule Ball games!
There are two Included Files, one is "HuleBallClient.gmz" and other "HuleBallServer.gmz"
There are documents about commands, just visit this topic: http://gmc.yoyogames.com/index.php?showtopic=642502
