Glitch. This game launched, and it made several people very happy, but it made its designers sad because it didn't feel ready for launch. So the designers called backsies on launch and took the game back to beta for more development and refinement. It's been nine months since then, and according to the latest developer update, the game is almost up to the point it should have been during its first launch... but not quite.
The blog post explains that there were three core things that the design team wanted in the game before the official relaunch: a better introduction for new players, imagination and upgrades as a core advancement system, and a better land and housing system. While those features are in place, they've just brought on new challenges for the designers and new updates that need to be added. The overall takeaway is that if you're not playing now, you will be able to soon, as the game is almost as the designers want it, and then we can all live happily ever after.
