THAT WAS SO STRESSFUL!!! I saw that I was at 14,000, my heart started pounding, and when I was right there, I choked and fell. I was so mad, but while I was falling it gave me the badge. It was incredible. If I would've fallen 1 platform earlier I would've not gotten it, but instead I got 15,044 and a crazy story.
In response to why it's not working- It gives me a screen that says "Sorry, Chrome can't run this app". Unfortunately, I'm not able to use Firefox either because it's cluttered with adware and toolbars that I can't seem to remove.
