Nice art and interesting minigames but it's quite unoptimized, especially seen in staff list which lags like crazy the more staff you have also some clicking triggers need fixing, its easy to misclick. But the biggest turn off is the high importance of gems in contrast to its very limited gaining options. By the time you reach the penultimate upgrade you will have no other choice but to farm a very mindless minigame. Even daily logins stop month later...
