From the developer:
One Late Night is a short immersive horror-game experience, starring an unnamed graphic designer employee, working late one night at the office, until strange things start to happen.
The basic idea is that players who have been in similar situations, and worked with similar office jobs, will relate themselves to the game setting and scenario and become immersed.
