This game is cute and it used to be fun. I liked that if you watch many ads you can get more rewards like getting speed boosts in the mines or in battle, that's a nice touch that I haven't seen in other games like this. But the regular ad rewards have been lessened and the ads don't work half the time. The grind has become not worth it or fun anymore, I hope these issues will be fixed in the future.

Game is fun, but then it gets repetitive real fast. Definitely do more losing then winning when you get to later levels, simply because it requires you to buy stuff to stay on top of it. If you don't buy you have to watch upwards of 40+ ads a day to stand a chance and even then it takes forever. Also idk what about it is "idle' because you will prematurely lose every single time If you "idle".

Hello! Making in-game purchases only speeds up your progress, it's not the only way to get ahead in the game. There are plenty of other ways to earn in-game resources. So, if you're an active player, you can still compete with others. Good luck!

When ever something is offered by watching an ad, I watch it and I don't get the reward. I have to watch an ad 3 or 4 times to get the reward to come through. Also the lucky wheel freezes and I have to shut the whole game off and restart. It's annoying especially sense I've put a couple bucks into the game already
