What real reviews say
★ Not worth playing anymore Have played the game for over a year, i have now got to a point where it’s going to take 2 years to upgrade to open the next door!!!!!! Not worth the time to play anymore!!!! We need more access to more blue core material
★★★ Fun at first … then boring This game started out fun. It was unlike anything I had played. Progress was easy, goals were achievable. Now that I am quite far along, though, it has become a boring slog. It is a resource chase game where you have to spend days and days just getting to the next step. I have been stuck on the curr
★★ Pop-ups ruined the game Had this game for years. Pulled it up one day to be bombarded with pop-ups every few minutes. you have to be special kind of incompetent to think users want to be interrupted when doing a task. Delete lol
