Find the Difference Game was a freelancing project for Dataware Games by using the Unity game engine. My task was to build the game so that it can be easily used for making similar games only by changing the graphics.  One of the main responsibilities I had was to write a custom shader for masking sprites and work with Matrices in order to transform from screen space into image space. The game is available on PC, Android and iOS. Moreover in order to be sure that the game would run on every mentioned platform I have implemented a feature to the interface in order to scale it accordingly on different resolutions.
