There should be a way to give an app a ZERO because this one deserves it. The game is great, but if you watch an ad video, the app will triple the regard. The ad was 1 minute long, and when I went home for the reward, another 30-second ad. And then another add. Forget it; your app is ad hungry and annoying. This happened multiple times . Also when I was to add a reward after a long video, the app crashed and no reward when I made it back. Seriously, fix it, sort yourself out. You get a ZERO.
