Summary: Zoo Keeper is just like any other sim: Take care of animals and earn money. However the zoo seems to be more focused on the zoo itself than the animals. There are no penalties for mistreating the animals by not feeding them. Also, the number of people that visit your zoo is time based, leading to the player doing the required daily activities then setting the DS down so the zoo can get more than 25 visitors a day. Playing the game itself can be frustrating.
