Pou Horror is a horror game inspired by Pou, the popular virtual pet game. At first, the game appears to be a typical pet simulation game in which you care for Bou by feeding, washing, and playing with him. However, the game swiftly shifts to the horror side when bizarre and terrible events occur. Players must solve puzzles and face challenges to escape the haunted house. The game uses simple controls, such as WASD to move and a mouse to interact. In the game, the E key and the middle mouse button also play an important role in solving situations.
