    ain't great, ain't bad. no forced ads yet but plenty optional ads that get shoved in you're face to get rewards. also tries to lead me to stuff that I need currency that I need to pay for. despite the rampant mindgame marketing going on, the gameplay itself is actually quite fun and addictive. if only they stopped trying to draw me away from it after every mission...
