The following glitch removes the 'PREV' symbol allowing you to use a specific employee an unlimited number of times to do a certain job of game making (scenario, graphics, sound). When you are going to make a game and you are prompted to pick an employee to choose a scenario, press 'back' on the bottom right. When you tap 'OK' again on the 'Game Direction' window you will be prompted to pick the employee again and you will notice that no employee will have the 'PREV' symbol anymore.
