This was a fantastic game. Grindy for sure, but it does exactly what it says and the ads aren't forced. But then I opened up the game today and all of my recent progress was gone. The game sent me back several levels (and removed access to the new area I had unlocked) without any reason. It's incredibly frustrating to have tons of progress taken away in a progress-based game, especially one that depends on grinding. I would not recommend trying this game unless they fix whatever caused that.

so I was playing for a bit not hard at all, decent graphics and what not. But here's the problem, you call it an idle game and no matter how long you're off you won't idle. you literally have to keep the game on 24/7 if you want to progress. Also, after lvl 4, it's nearly impossible to move on. you need 30k or more to lvl up but the most XP you get is 11. not worth playing long game but for an hour or two and that's it. After the hour or so just delete the app bc you will not make progress.

Great idle game to ignore adds on, there are tons of them and there's bugs that make the game freeze in ads. That's good fun. The shop button constantly gets hit when trying to chase or outrun enemies, damn button is right where it gets hit by the thumb corner of my palm when I try and move with my left thumb. I wouldn't invest money but it's honestly a good short term distraction if that's what you're looking for. Sorry I couldn't say better. The ads do give great rewards though so thanks.
