TwinOfTime is a sci-fi themed parkour and puzzle game built around cooperative gameplay. The game takes place inside a massive, abandoned laboratory set in the future.

The story begins with the use of the reactor’s last remaining energy. By using this final power, the character summons their past self into the same timeline. As a result, two characters emerge—not separated by time, but split within a single timeline. Both the game and its name, TwinOfTime, are born from this idea.

The shared goal of the two characters is to restore the reactor by solving electrical failures, broken systems, and environmental issues scattered throughout the depths of the laboratory. To achieve this, players must locate required components across different areas, repair power lines, and synchronize systems together.

However, the experience is not limited to puzzles alone. Over time, survival challenges such as hunger begin to emerge. To stay alive, characters must find food and consume it at the right moments.

Throughout the game, players will sometimes carry heavy objects together, sometimes perform parkour across high platforms, and sometimes solve physics-based environmental puzzles. All of these mechanics are designed to require communication and strong teamwork.
