The game is fun for tbe first 30 min, after that it's just an Ad hell, you want the game to go faster? 1min ad, you eant to claim half of your dailies? another 1min ad, its just ads for everything, everywhere, and on top of it they have the pair to make the ad removal $30, and if it wasn't enough, you hit the F2P wall pretty early on. there's better options put there, good looking game, but this sickening greed on phone games is what makes them this unbearable.

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.

Identical to every other cash grab idle game. Riddled with countless dark patterns like the rest of them. This game is designed to be addictive and to manipulate you into spending large amounts of money, not to be fun. If developers respond saying otherwise, it is an outright lie, as otherwise those features would not be present in the first place. Not worth your time or money.
