Great point - "or" does make more sense. I've updated it - thanks for the feedback.
The highest score I'm aware of is 109,541 with a x185 streak, which absolutely destroys my own personal best of 16,519 with a x81 streak.
I know some other developers are maintaining websites with weekly high scores and using google forms for submission since side-loaded games can't do it on the device (yet). I'll give that some thought.
