Tower of shadows is a  2-players local multiplayer co-op  puzzle game (also playable in single player mode), where you play with a friend as a character in the real world and it's shadow  in the shadow world, working together to solve multiple puzzles and escape a magical mechanical tower.

The Tower is built by the elements company which assigned two of it's "best" employees to guide you through your journey, but they are aware of their existence in a video game so the narrative of the game is done in a comical and meta narrative manner and constantly breaking the forth wall.
