I've never even heard of Pocket Legends before, much less the developer.
And what point are you trying to make? Their game is getting 12-13k downloads per day and has made best-of lists on Mashable and MSNBC; clearly they are well known, even if you are not personally aware of them.
I'd never heard of them before either. They're clearly doing a great job in the mobile space, but when I read "well-known game developer", I think of companies a few orders of magnitude larger than Spacetime.
For a company with wider brand recognition - whether it's Rovio (Angry Birds) or Blizzard or Harmonix (Rock Band) or whomever to do better on Android than iOS, that'd signal something a bit larger. Which is what I was expecting this article to be about.
