Not bad and nice graphics.... I have a fast tablet i play plenty of games on... This takes ages swapping between screens.... Also ads.... Yes, most are optional, but to get a x5 boost you watch a video.... But wait, you want a boost on the next building.... Another ad.... And upgrades to buildings don't seem to have a predictable effect on income... I double production and income barely changes... Maybe I'm missing something, but too many niggles so sorry, uninstall
