Horror adventure Best Friend takes place in three-dimensional space, and the main task is to escape from a doll named David. It all happened when the child stopped wanting to play with the doll, which is why it got angry and began to chase the owner. The user will need to run away from hostile creatures and encounter paranormal phenomena. The only advice the protagonist needs is not to turn his back, otherwise the enemy will instantly reach him.

The gameplay offers exploration of a rather large territory, where many useful and key items are scattered. The gamer will encounter screamers and hear terrifying sounds that enhance the horror atmosphere. The adventure has several main tasks, such as finding 3 things in the form of a donut, an apple and a ball. Without them it is impossible to complete the journey. The interface helps you locate key items, and the tooltips tell you their approximate location.

The gameplay is divided into two stages. In the first episode, the user will need to survive until 3 am, and also have time to collect three things. If the mission is completed, then the second phase of the adventure begins. You need to live in it until 5 am, and the difficulty will increase significantly. The enemy will react faster and better to sounds and noise. After the character survives, he needs to eat the pie that David made, this is the only way to get along with the doll and not lose his own life.
