I bought it, downloaded it, opened it in galaxy app, pressed play, and it scrolled down the page to the overview video. no game. Tried uninstalling and reinstalling, but still nothing. Any help would be appreciated.

I don't have this problem, but it doesn't work on my integrated Intel graphics very well. I play it on Luna to get around that, so that's and option.

It's possible it is crashing immediately. Are your graphics drivers up to date?
