What real reviews say
★★★ VERY Fun but VERY Infuriating This game has an incredible gameplay loop and is absolutely a blast to play. BUT; there are multiple HUGE issues that impact my enjoyment heavily. First, it’s entirely luck-based. I paid $70 in in-app purchases just to speed up my progress, but the only thing that actually gets me through a hard lev
★★★★ Good but tiring I enjoy the game a lot but it’s so tiring with all the sub-menus and advertisements trying to making you spend money. Why not make a good game and pay once? Takes me ten minutes just to click through everything to collect what I need and be confronted with all of the “pay for more” buttons…
★★ AI Cheating The game used to be fair. Now the AI just straight up cheats during the events. Been playing for quite some time and investing. If cheating happens, I’m glad to spend my money elsewhere.
