I've played similar games. this one relies on ad watching and clicking here and there. just to do your daily quests, get equipment and so on if I say 100 ads could be enough to get all the stuff. there are few packs to spend money on, but on the high side. 2 stars as it is not too boring, still idle game. uninstalled due to high number of ad watching requirements.

Hi! You can choose to watch ads or not by your own will. Ads can be very annoying sometimes. We wish we could disable them forever. At the same time, ads allow us to maintain the game, add new features, and make it available for everyone without any charges! We hope you can understand that. Thanks for your patience and support!

was really enjoying the game for the most part. the endless ads are a bit annoying ( no I wont pay for no ads) It's the fact that you can only get the strong characters by paying for them! $10 to $20 for a decent characters is insane. I liked the fact there's no guilds to deal with. But at some point no matter how strong you build up you won't do enough damage.
