a pet shop after dark sends the player on a horror adventure, where they have to do everyday things and never turn off the lights. This is required in order to stay alive. The main character receives the task of watering plants and feeding animals in a store remote from the city. Everything seems normal until night falls and an electrical problem occurs.

Exploring the world and interacting with the environment takes place in a point-and-click style. The user will need to hover over a certain object with the mouse to understand whether it can be interacted with or not. Items can be rearranged from one place to another, as well as put into inventory, which can be used in the future passage. The gamer must explore a mysterious pet store filled with animals and oddities when the light goes out.

The gameplay will include puzzles and dangers that you need to avoid. The central character will water the bizarre plants, as if they came from an alien world, and also feed invisible pets. There is a set of rules that the player learns about as he progresses, which helps him complete the task and stay alive in a dangerous environment. The goal is to survive the entire night, which gradually increases in difficulty and presents more challenges.
