In this game, you can build your own dream park with lots of rollar coaster, shops, merry-go-round, beautiful games, etc. You can design your own rollar coaster with any colour and can design your own park. Except this, you can also kill people in your park. You can build a non-finish rollar coaster and then start it, when the rollar-coaster-car reach there, it will throw away and 'BOMB', all the people in the car will die immediately! But this is a healthy game for children and kill people will diminish your park's rating so I don't think you should do that.
