The game's fun in terms of it's designed to not let you let go of your phone or exit the game. It's addictive. My biggest issue is a lot of times when you watch ads for rewards it doesn't count. Huge waste of time. Maybe it's because the ad was too long that it considered me afk. Uninstalled because of this. Happened way too many times. And when you get to contracts, it's absurdly pay to win. No amount of managing your resources and upgrades will make you reach goals. It forces you to buy stuff.
