Zero Sum is a puzzle game with a variety of twists. First, there’s the storyline about a student and professor who discover the cure for cancer together. Then it gets stolen!
Players will re-discover the cure for cancer by solving number puzzles where the goal is to get equations equaling zero in the end. Then there’s the fact that the developer is promising to donate half the proceeds of Zero Sum’s sales to the American Cancer Society.
The game also happens to feature a weird FMV aesthetic which is always fun. Check out the Steam Greenlight page for more information.
