Seed is game I made with three friends (Hadrien Saiget, Jonathan Toti-butin and Sophie Conchonnet) for the 2013 Microsoft Imagine Cup competition. We earned the Gold Medal during the French finals and the Bronze one during the International finals.
In Seed, you have to help a joyful bouncing seed through several levels by means of a bouncing jelly and a grapple hook.
My role on this project was to code the entire game from scratch in C++. Everything from the engine to the tools has been made by me.
