Strange Silent Cafe Night Duty

This is a psychological horror game about a student working late nights in an internet cafe.
You play as a young college student who needs money to pay for school. To earn some extra cash, you take a part-time job as a night shift clerk at a small internet cafe. You often arrive late, and the manager talks to you in a strange and uncomfortable way.
Your main job is to take care of the cafe — clean the rooms, remove dirty stains, throw away trash, deal with customers and keep things in order. But the cafe isn’t normal. As the nights go by, strange things begin to happen. Customers sometimes act very weird — or even scary.
The deeper you go into your job, the more disturbing everything becomes. Is it just your imagination? Or is something really wrong with this place?
Can you survive the night shifts, or will you lose your mind inside the cafe?
