Good, needs work

I like this game, the art style and premise is super charming. I love that there’s a lot to do (filling orders, building the town, and raiding other people’s towns) but there is a drawback.

Waiting on your energy to refill is insane- it takes FOREVER to get one energy, let alone more. I want to play more, but with how skewed the energy system is, unless you’re willing to spend money, you’re out of luck.

I hope the devs fix this, otherwise i’ll probably end up deleting this game.

Developer Response ,

Thanks for your feedback. There are many different ways for you to earn extra energies in the game. For example, you can gain daily free energies from your friends, or join different free in-game events to earn energies. You can also earn extra energies by visiting our facebook fan page. We give out free energies on the fan page every day to all players. I hope those tips could help you.

Constant restart

I really like this game but I constantly have to restart it while playing because the game is constantly freezing and saying it is out of sync with the server. It gets tiresome to do every 2 minutes or less. Please fix the bugs in this game so I can play it without constantly having to reboot the game.

Developer Response ,

We are really sorry about this but please upgrade your game to the latest version we just released yesterday and it would be much more stable now.
