silkbulb test [demo] by Tim Oxton is a free-to-download first-person demo featuring a branching narrative, with every choice affecting the atmosphere. In this unsettling adventure title, you awaken in a classroom, sitting at a desk with a timer and  “A” and “B” as well as a projector in front.

Questions to answer

In silkbulb test [demo], true-or-false questions are answered by clicking “A” or “B,” and some of them are bizarre. For example, one question asks whether a photo of a baby or couple is a door. When a calibration key is displayed on the projector, the button combination must be followed.

You’ll get to explore dimly lit corridors, too. While the game’s strobing effects amp up the immersion and fear factor, some individuals will not like them. Though players can disable these effects, those with a history of photosensitivity should think twice about playing this title.

Play through the end

If you love horror games with branching narratives, silkbulb test [demo] is a title you should consider playing in your spare time. The first-person perspective, unsettling atmosphere, and bizarre questions heighten immersion, which is great. However, the lighting effects are a drawback for some players.
