[Overview]
"CUPLEX" is a time-shift action puzzle game where you cooperate with "your past self" to reach the goal. With every turn, a new past self is added. You will utilize them effectively to solve carefully structured puzzles that reward logical thinking.

------ A Fusion of Calm Atmosphere and Puzzle Design ------
In CUPLEX, we have placed strong emphasis not only on the puzzle mechanics, but also on the visuals, music, and story. By thoughtfully integrating these elements, the game creates a calm, reflective atmosphere that enhances the puzzle-solving experience. The game features a total of 36 stages across six distinct layers, each containing six stages. Every layer is designed with its own unique atmosphere and puzzle theme, offering variety while maintaining a cohesive experience.

------ Support Features for a Smooth and Focused Experience ------
To help players concentrate on the core puzzle mechanics, CUPLEX includes a variety of assist features. For example, “Visual Support” uses symbol markers to clearly show the relationship between switches and their corresponding mechanisms. The “Trail System” displays the movements of your past self, making coordination more intuitive. Additionally, in the Library (stage selection area), “Scope Mode” displays objectives and stage names, ensuring that players always understand their current goals and never lose sight of what to do next.

------ “Past Interference” — An Action That Alters Your Past Self’s Behavior ------
In the later stages, alongside newly introduced mechanics, players gain access to the “Past Interference” action, which allows them to deliberately alter the behavior of their ghost (their past self). This mechanic expands the range of possible interactions and enables more intricate puzzle designs, offering a satisfying challenge for players seeking greater complexity.
