Psychomanteum

Every year, your friends hold a Halloween party, and each guest must complete three dares. The Psychomanteum is new: a mirrored chamber, in which you must stay, in darkness, for an hour. That shouldn't be too bad, right? You're a connoisseur of haunted houses and all things Halloween, after all, so nothing should really surprise you.

This game has all the usual trappings of Halloween - pumpkin spice, haunted houses, darkness. This contrasts with the genuine sense of increasing derangement as the PC spends more and more time in the titular box.

Psychomanteum has a strong concept, aided by the background music and sound effects. There were some disambiguation issues, if memory serves, and I didn't know what to make of (Spoiler - click to show)the slate. Psychomanteum leaves its truth deliberately ambiguous, but presented some deliciously creepy possibilities.

IN this game, you're trapped in a mirrored box as part of a Halloween stunt, carrying only a candle and some matches.

I couldn't get the game to do much, but it really had atmosphere. Just the act of lighting the matches, and the candle, and having the descriptions of your reflection described, were subtly creepy.

This author really knows how to use minimalism to create an atmosphere of the eerie & the liminal...
A short piece with a novel concept, it features a limited environment but a very well implemented one, used to heighten the tension. Effectively written, and with several endings depending on what is done.
