Steps

Find a way out of the location, moving in complete darkness. The sounds of your footsteps will tell you where to go.

P.S.  
After publishing the game, we realized that the beginning may seem intuitively incomprehensible to the player.
When you start the game/move to a new level, you see a black screen. This is not a download bug or an error. To understand what needs to be done, start moving on WASD or arrows (you need to walk a certain time), then you will see what our game is!
