This is a local multiplayer game, for the blue tank it is W,A,S,D to move and F to shoot, for red tank it is arrow keys and L to shoot, and space is to change the map, the rest you can figure out on your own.
Thanks to irmirx to making some sprites! http://opengameart.org/content/top-down-painted-tanks The game might be a bit laggy, sorry if it is. This is my first game I actually spent some more time on, and I never thought all my forever loops would cause lag.
