Our take on Duplexer
The defining mechanic is environmental manipulation: players physically shift sections of walls, floors, and ceilings to alter routes and position objects within each level.
What is Duplexer?
Duplexer is a single-player puzzle platformer built around moving parts of the surrounding environment.
Players push or pull sections of walls, floors, and ceilings to navigate levels, reposition objects, and overcome platforming and physics-based challenges. The game includes 100 levels, each with a built-in timer for recording completion times and support for replaying completed stages. Its structure allows puzzles to be approached through different movement and positioning methods. An original music score accompanies the game, and 21 achievements provide additional goals. The game is intended for speedrunning, with level times available for comparison during repeated attempts. The vendor also plans to release additional levels in future updates.
