Did you "buy" that land on the game using ETH? Have you checked their social media channels about possible news and updates on any bugs?
Worst case scenario, the owners decided to shut down the project and run away with players money. I guess this would not be the first time a dApp scams its users. Previously many faucets and all were doing the same thing. One good example was Cowkeepercoin.
Either way, you can make a scam accusation report if the owners have an account here to make other users aware of the possibility of scam. But it would not help recover any money. Legal route is there too, but that is a big grey area.
