is addictive, but seeehhhrrr lengthy and disproportionately high repair costs

I'm now at level 18 (of 40 obviously possible levels). Contrary to my usual habits I have about 30 invested in the game, I would not come without real money. Unfortunately you have to pay a lot to have a real benefit. (I used the money to expand the country).
the game itself is well done and makes especially really addictive. In addition, you do not need FB friends, but plays all alone for themselves and iwann the game is over.
negative is the fact that you have to invest money from Level 15 at the latest, otherwise you will not progress. I could live with, but it annoys me that the building constantly get broken and must be repaired. the repair costs are disproportionately high. eg I have to repair the witch's house about every 10 times. Yield: 800, costs for repairs since 35000. But what can not be true!
