ABOUT THE GAME

How to take the road you see

The protagonist, wearing a white coat, walks through a dark space separated by stone walls and floors. At the end of the passage extending left and right, you can see floating scaffolding and a narrow path under the floor. It's a 2D exploration action game where you use movement and jump while looking at the terrain to find the golden mark.

01

There is an upper and lower path at the end of the passage.

Beyond the flat floor, there are scaffoldings lined up above and a narrow space under the floor. Even if you see a gold mark nearby, if there is a wall or floor separating you, you will have to find a way to approach it.

02

Add transformation key to jump and attack

In addition to movement and jumping, it uses Z or right Shift to attack, and X and C to perform two transformation operations. You can check the key assignments for movement, jump, attack, and transformation on the operation chart on the official page.

03

Read terrain and symbols more than words

The main screen is centered around the main character, scaffolding, hearts, and the number of items collected. The official page also states that the game is textless, and rather than following a long conversation, the game involves directly interacting with the visible space.
