Andrew "Andy" Sum, also known JigxorAndy  or simply Jigxor is one of the developers of Crossy Road. While being one of the co-founders of Hipster Whale, Andy has also created games such as GAME OF THE YEAR 420BLAZEIT and Dungeon Dashers.


As a child, Sum's dream was to become a game developer. He remembered always being fascinated with games, and at a very early age he began making games as a hobby. Once he started becoming increasingly adept with these creations, he made a definite decision to turn it into a career. He began his indie projects when, as he relates, “I had an itch nagging away at me to work on my ideas. There came a time when I just had to try and build them.”[1]

Andy Sum is currently 24 years old and lives in Melbourne, Australia. He is a programmer and uses C# with Unity3D. He is studying a Master of Engineering (Software) at The University of Melbourne. Andy is currently working on Crossy Road and a turn-based dungeon crawler game for PC, called Dungeon Dashers.[2] During the development of Crossy Road, he was responsible for the game and sound.[3]

In his free time, he enjoys watching movies and playing games, such as Overwatch. He also enjoys coding prototpyes for new game ideas.[1]
