About this 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.
