Does anyone have any pointers for putting up decent scores on this game? I've had mine for two months, it's in good working order and I haven't even come close to putting up a high score on it yet. My best score is 1.7 million but my usual game is around 200-400k. I'm not a great player by any means but I usually can put together a decent game every so often on any machine. So far, Space Shuttle has shut me down. And I love it by the way--the game, not getting shut down. Any pro tips?
