Remove the "PREV" Symbol and Use an Employee Unlimited Times
This glitch removes the "PREV" symbol so you can 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 pick a scenario, press "back" on the bottom right. Now tap "ok" again on the "Game Direction" window and you'll be prompted to pick the employee again. You'll notice that no employee has the PREV symbol anymore.
Preview result of Genre/Type Combination
Select a combination of Genre & Type and continue until you are prompted to pick an employee to make a scenario. Press "back" on the bottom right. Now you can see the result of the combination of Genre and Type, without the need to create a game, allowing you to search for "Amazing!" combinations.
Hire New Workers For Nothing
Use the "Word of Mouth" hiring. After all your spots are filled, get the best possible hiring you have. When going to hire someone and it tells you that you have to fire someone, fire whoever and pay nothing! No money will come out of your account; perfect for new games.
