I'm aware of what it runs on. FWIW, the Epic has unofficially had 2.2 for a bit now, with the official coming on Sunday.
I was just relaying what the devs of DD (Trendy Entertainment @trendyent on Twitter)) had to say about the game at 8am this morning when v1.0 was released. Which was, if you didn't have a supported device running 2.2, you, wouldn't be able to download it. That was rectified a couple hours later when 1.1 was released which enabled supported devices running 2.1.
It's all a moot point now as all of the supported devices can now see the app in the market and play the game.
