I like the concept and the graphics are, for the most part, pretty good (the tourists look like trolls for some reason?). The problem is the upgrade system. You have to use both coins and gems (the premium currency) as well as wait an hour and a half for it to be 'delivered'. And that was just the first upgrade! I can only imagine how many hours you have to wait later on. If I can't pick up your game and play it whenever I want, what's the point? ETA: time management irl is a job, not a game :)
