The game is a 2D sidescroller with simple quests involving characters from everyday life in São Paulo. The setting is horror-themed, featuring eerie art and soundtrack, and jump scares to increase player anxiety.
The game features a main character (Glória) who is returning from her work as a night shift nurse and encounters a malfunction in the last train of the night. She gets stuck in the dark train and can't get out. The train announcer explains that passengers need to evacuate as quickly as possible as they are in grave danger.
From there, the player must help the NPCs trapped on the train so that, with everyone's help, they can escape unharmed. During this task, the player will be challenged by a monster that will try to prevent this from happening, and Glória's mission is to complete the quests while avoiding being seen by the monster inside the train.
