Kodansha Game Lab and Octorain have announced new 2D action puzzle game TrailRail launches in summer 2026 for PC via Steam. A free TrailRail demo is available on Steam.
Lastly, here’s an overview of the game, via Steam:
Your “Footsteps” Become the “Path” That Changes the World
TrailRail is a 2D physics-based action puzzle game that uses a system to materialize the player’s “movement trail” with a single button press.
You play as Rail, a girl who has lost her memories, advancing forward to discover yourself and the world.
Solve 38 Deeply Engaging Puzzles with Simple Controls and “Insight”
Controls are limited to “Move,” “Jump,” and “Materialize Trajectory.”
Despite the simple controls, 38 stages of puzzles await, where your “inspiration” is essential to overcome them.
Turn your flight path into a bridge, or draw a circle to create a foothold.
Materialize your envisioned ideal trajectory, then use actions like “Push,” Pull,“ ”Rotate,” and other physics-based actions to solve puzzles and advance through the stages.
The key to solving puzzles lies in the “discoveries” and “chance encounters” born from your intuition. Clear every stage to uncover Rail’s origins and the mysteries of this world.
