When a spirit is around, the girl's heartbeat will increase. While exploring, the player finds items and strange 'spirits', who are lurking in various places such as shades of mountains, street corners, and below a street light, and sometimes attack the player. The only source of light is a flashlight. Players explore a town at night in order to bring the two girls back together and find the way home. The actions, decisions and information you get from playing as one will impact the story of the other. As the story advances, the player will switch between the perspectives of Yui and Haru. Mustering up their courage, the two girls explore an ominous night town which is completely different during daytime and where someone is lurking in the shadows. When they let go of each other's hands, they got separated.

A similar effect was achieved by real-time gameplay, where the player must react to everything that is happening taking into account the situation, and each decision can change the sequence of events.After going to a late summer fireworks festival together in the mountains, the girls Yui and Haru got lost on the way back home. What is the explanation for such a keen interest in adventure interactive history? First of all, of course, an intriguing plot, a charismatic character, but most importantly an illusion of the reality of what is happening and immersion in the atmosphere of the game. Of course, such success could not remain unused and the developers literally released the sequel in a few months, and then a third part called Lifeline: Silent Night or Lifeline. At the time of its appearance, the first part of the series Lifeline has made a real revolution in the field of mobile games and as a result has won simply unprecedented popularity.
