Last night I doubled my old high score..... it's very addictive. My old old highest score is now my lowest score on the personal leaderboard. For those of you who haven't heard the music change a couple of times.. that is definitely one of the awesome things about this game. The action really ratchets up along with the soundtrack. I find myself playing "just a few more times" so I can feel the rush of the music again and see where it ends. Right now I'm not sure!!! The important lesson, yes. This lesson is the key.
