About the Game

■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 over 35 stages of deep puzzles with simple controls and flashes of 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.

■Characters

・Rail

The game's main character.

She woke up in a dilapidated laboratory, but can't remember who she is or why she's here.

After realizing her name was "Rail" from the name embroidered in white on her coat, she embarks on a journey to escape the laboratory with the only remaining functioning robot.

・Bot

A robot that was in the laboratory where Rail woke up.

It can't speak, but seems like it's able to express its emotions.

It has the ability to materialize movement trajectory.
