Yup...
After playing this for a solid 3 hours, I pretty much got to the point where you couldn't go any further. I was up to a 6.2x speed and I started losing. It got down to 2 games. The one where you dodge the 3 green balls, and the one where you bounce on the things as they go by. I stayed in these 2 games up until the 8.2x multiplier then finally gave up. I posted my score, and for some odd reason it isn't going through. But either way, great game. Love it.
