3 stars: Progression through game is real fast. Relatively quick to earn money. However, I find battery usage is high, even after changing a bunch of settings. Graphics are cartoony and simple in some places. I enjoy the management aspect of the game, game is quite addictive. App however is filled with game purchases, some of which are not worth it. It is really a pay-to-win game in many aspects.
3 stars: This is a good quality game with a good simple concept. However, this is marred by the downright predatory microtransactions that prevent one from advancing at a reasonable pace when you get to around level 8. While I refuse to shell out any money for this game, I would not be against paying a one time fee of 10 to 15 dollars to purchase it outright without the microtransactions.
4 stars: Great game. The only bugs I have seem to found is that the mechanic to watch an ad in order to get an extra driver for an hour does not work. It never shows an ad for me. Also, when shipping supplies I wish it was possible to set a number. i.e. i only want 8 apples for apple juice. Other than that, I love this game.
3 stars: Addictive game. But, over the time I have been playing, I have seen many issues. Server problems, lost progress when updating, and not showing progress properly for tasks. Updates sometimes cause more problems than they fix. It has become very frustrating for many of the core players.
4 stars: Great game! Not significantly pay to win and very enjoyable! ...
