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. Even if you can't relate to the game storyline, you will still get a good experience. The storyline is presented with short monologues, displaying the thoughts of the player, as you need to perform certain tasks to proceed in the game to continue discover new clues about what's going on. Use your surroundings to your advantage and hide under desks and in corners to avoid being taken by the ghost which haunts the office. Remember that the light will always be your friend. Survive the night and find as many clues as you can about the threat.
It's rare that I give a game such a high rating, but I have to say, Slender never terrified me as much as this game. The atmosphere brought so many questions. Was that knocking noise the monster about to break in and chase me? What does the music mean and why has it suddenly turned bleak, does that mean the monster is close? The biggest question this game gave me is probably one of the most effective impacts it had on me: when will the monster come back? That simple question was enough to drive me crazy with fear and always kept me on edge. Slender never had as much of an impact on me as One Late Night did, I still felt that cold rush of fear even after the game was over, like the monster was still waiting invisible and ready to suddenly appear. This is the kind of fear that must always appear in horror games, not just cheap jumpscares (although there are a few minor ones in this game). This is a true horror game and it deserves to be recognized as such. I hope the developer still has plans to make another game.
