I don´t know why but everytime I buy a fence doesn't work. I mean the bug or problem is that I have to buy the fence 4 times just to appear once. The game is beautiful but the best strategy to survive is the more monotone and boring one. By that I mean not buying sheeps, not buying fence, not buyin anythin. Buying one sheep is just good if you dont lose other sheep in 5 rounds or days. So the best way to survive without finality is just making the possible to not lose sheeps and hold the more days possible saving money just eating the minimum. One run time is fine but it goes monotone. Open the gate and awaken the dead has no end but to make the game more difficult and it has nothing to do with the story. I know that because after 12 rounds just saving money and not buying anything I've reached 100 coins I spent 45 just to one fence and that is frustrating. Even after that I had enough money to open the gate sacrifice 10 sheeps and thats it all done just again at the beginning with less money. Conclusion: The game is hugely beautiful, really is and I apreciate the effort. But buying sheeps and taking the risk of losing it before 5 days doesn't worth it, the same goes with the fence, apart of costing too much you have to buy 4 just to get one, and the low part of the house not even mentioning. If the gate is open and you don't have at least 30 coins saved you dead.
