Players generally enjoy the story of Inmates because it is interesting and full of suspense. The game follows Jonathan as he explores a broken-down prison and uncovers a psychological mystery involving different personalities and a strange child. Many players compare the story to the movie Identity because of its surprising twists and tense atmosphere.
The horror focuses more on the mind than on scary monsters or constant jump scares. The game uses background sounds, notes, and tense situations to create fear, and players feel the jump scares are used only when needed. The prison is detailed and immersive, and the sound design helps make the environment feel creepy and unsettling. Collectible notes and diaries reward exploration and add more details to the story.
However, many players criticize the gameplay. Movement is very slow, and there are no options to run or jump, which can make exploring the prison feel frustrating and less enjoyable.
