I have finished my game Tank Arena. It is a very easy to play, multiplayer game (played on the one keyboard) which can be downloaded from my website at this address.
All instructions are in the .zip file you will download. Screenshots of the game are on the website.
Please post feedback, it will come in handy when I go to make better versions of the game.
Lastly, I hope this is where this sort of post is supposed to go, if not please tell me and I will move it to its correct place
