Well... yeah, it is unfortunate. A lot of people would want the game to be out already, but it's problematic. We're a team of two, and we feel key features are still missing. Those can't be added to the chain any more after the release of mainnet. Neither of us are working on this full time, as we have "dayjobs" so that complicates things :/

So it's just because people keep asking if it's mainnet and if their mined coins count - I don't want people to run their hashrates for testnet coins unnecessarily. The game supports merge-mining with Monero though, so that helps things.

I just don't feel like setting a date for mainnet release. It's so hard to estimate when the game is ready enough to have all the ingredients in it to be successful and enjoyable - it'd be different if we were a company working on it or so.
