This does sound cool... but the play button brings up both options to buy the game for $20, as well as download links? I think $20 is too much for an early alpha. And while I get that many MMOs are downloadable native code, you wrote it using a stack that could be web-based, so that is probably the way to go. Asking people to download and run an .exe is a non-starter for many of us. Too high-risk.
