it was pretty fun till day 10. No apple-supply and so no wining possible ...
Even after reloading no change to win without new apples.
Further more the train should come after each fail. I could collect many coins and gems but i couldn't improve my army because i always lost level 10. And after a reload everything i had collected was gone. That was pretty strange. Either the items collected stay between the trys (but than the train should come every time to improve the army) or everything collected is lost if the town gets over run. As it is now it doesn't make much sense.
That plus the bug on level 10 gets you some stars cut off, but never the less 3.5/5 stars.
