Game Trailer

Simple Controls, Over 30 High-Difficulty Stages

Players use left and right movement, jumps, and slashes to clear more than 30 stages and collect their scrolls.

While the controls are simple, enemies and hazards such as spikes are placed throughout each stage, and a single mistimed move can end a run.

It's a high-difficulty action game where players gradually improve by memorizing stage routes and control timing, offering the satisfaction of clearing a stage after repeated trial and error.
