In My Big Friend, you have to help your big friend fix his time machine so that he can return to his world. Jump between the past, present, and future, collecting gems and items that will allow you to explore new areas of each time period. Each time period is represented by red, green, or blue, which is also the color of their respective gems. Some gems are in plain sight, while others can only be obtained by picking locks. Can you collect all 45 gems?
