Unplayable. I know you need income to run the game and so on. But your ads to ridiculous. Instead ads each time change area its more reasonable with an ads on each passing days. The ads that sometimes in potrait mode and sometimes in landscape mode create a heavy burden to phone. Its fine if the ads aren't to often, but when ads popped out each time you change area was a problematic issues. More or so Blank screen was the results of this crazy ads bomb.
