The game itself is really fun! I only gave three stars because I do tend to lose interest due to how long it takes to regain energy. The 5 star tasks can take upwards of 90 energy to complete, so you have to wait for your energy to refill almost 3 times (this takes over 6 hours) to complete one activity, and most of that time is just spent waiting. The extra energy that can be found/won is just not that much. Unless you pay for additional energy, you can only play the game a tiny bit each day.
