I really enjoy this game and is the only game i play every day, multiple times a day. The only reason i gave 4 stars instead of 5 is because in some of the locations require so much energy i am only able to play for 5 minutes at a time.Yes, some of the locations are optional but it is disappointing not being able to complete the quest. For this reason i would never purchase a quest only to not be able to enjoy it. It is really discouraging and instead of pulling me in it makes me stop playing.
