I am the founder of a publishing company called Splashing Cow Books. We publish books for children, mobile apps and printed cards. The development team for our mobile apps is Magic Spangle Studios, who will provide the technical replies to any questions you have about our source codes. My role is to invent the idea behind the game. Magic Spangle's role is to convert that idea into a game. Splashing Cow Books is a new company, but Magic Spangle Studios has been building games for a long time. We are selling the source code to our first originally designed game, called Erupt-A-Cake. It is a classic catcher game, that tests reflexes and builds eye hand coordination in young players. It has been designed with Unity and is compatible in iOS, Android and Windows.
