With each new park, the difficulty of training employees and completing missions will increase.

Example: In the first level (Thrillville) cheerleading utilizes only the X button and the basic directions.(Up, Down, Left, Right)Later, you'll need to use the diagonal directions and all of the buttons. Mechanic training has pieces in the order you'll use them. Later, they mix em up. Groundkeeper traning is really the same. Many goals will require more specific stats to be increased: like profit, top ride speed, ride height, balance of attractions.
