Hi,
I finally managed to release my facebook game "Offroad Online".
It's basically an endless driving truck game with some cool features like highscores, quests and realtime multiplayer races against friends.
You can customize your truck with a lot of extra stuff, and destroy your friends trucks in real time races with many power ups like bombs and nails.
The game is in early beta stage right now, so I would be glad if you could report some bugs. Right now the game is only available on facebook. A non facebook version will be coming soon.
