I need some help finding a game

I use to play a game on game-tap that was like a space simulator but you could level up, and you would fight other ships, do missions, and trasport cargo. i can't remember the name of this game for the life of me. The game was played in a over head veiw and you could only move forward and backward no up or down. you start out at earth and are asked to join some space pirates. after you complet the first quest you can go and do whatever you want out in the uinavers you've unlocked. just wordering if anyone could help me out?
