A great puzzle game with simple controls and clean feel. Great job, especially as it is still only a trial version. If I am not mistaken, you entered the Ludum Dare 26 competition. Good luck! http://www.ludumdare.com/compo/ludum-dare-26/?action=preview&uid=14547
Player 1 starts the game off by throwing the jack (pink ball). Then the goal is simply to get your petanque balls closer to the jack than your opponent. Each ball you have that is closer to the jack than your opponents is worth 1 point. A 'quick game' is first to 5 points...and 'full game' is first to 13 points. Hope that makes it clearer. There are instructions in-game, but who reads them hey :)
It is Monday and my brain is not here. This is why I uploaded two versions of a game with bugs. Don't know how those old versions got published. Maybe when my brain returns we will find out. I think it all works now.
