The developer informed on twitter, about an hour ago, at 12 p.m. CET, that the maintenance is still going on and they need a bit more time to fix the issues with the databases.
Hopefully they can get fixed the problem by the afternoon, but don’t estimate to much. I work on a small IMHO Article to summarize the momentarily situation.
Suggestion: Better use your rest of the weekend for other stuff than waiting for a fix or raging about the moment status of the game. You’re better of without raging and wasting energy than doing so. If you want to refund then do so, I think the chances are high that you will get a refund because of the current state of the game.
