Is it actually possible to get one complete cycle of Base mode? I think not. I had a bloody good go at it, and beat all my previous high scores, but still didn’t manage to complete a full “loop”.
Then I played Advance Mode, and managed to get far enough in to break 100,000 points, and also unlock three new skins. After that, I played Heavenly Star (I think it’s called that, anyway) for a while until I died.
