Was a five-star game until expansion and updates. The expansion (desert) was great but very demanding and time consuming. Kinda boring because of that. And no rewards to further generators. Most recent update in prep for the love festival slowed my game to the point where it takes 2 minutes just to move to the next frame of the story/loading screen/action. The game is now unplayable. I've played every event until now and am upset that I can't play anymore. Will change again if this is resolved.
