So first of all, I just started playing this game yesterday. There was a problem where I'm fighting the normal 3-9 boss. I thought it was just my imagination. I cleared the data of my game and restarted it. I encountered the same situation, again. My attack level is already in 463 and it's damage should have been 6B plus. But then, it suddenly went back to 1.52B and the boss that I should have already been able to defeat became someone unbeatable. Is this a bug? I'm not enjoying this. Uninstall.

Copy past of other idle games with supidly pricy AD-remover. (27€) Permanent pop ups about this or that package. Animations are nice tho, still 2/5 quick deinstall on my part Edit: Gave it another try after I saw high ratings after few months. Nothing got better. ADs are at every single corner, PayWall is huge, ADs bugging the game, running for 30-60seconds, opening the app-store without me clicking on anything and so on and so on. Went from 2/5 barely bearable straight up to an ADS-Simulator

Hi! We share your thoughts. 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!
