As a pure text adventure, it's passable: a standard short horror story with a twist of the type that now litters the internet. The parser is awkwardly non-standard (use LOOK ROOM, LOOK <object> and GO <location> instead of LOOK, EXAMINE and compass directions) and causes initial frustration.
But it's not a pure text adventure, it's displayed on a monitor screen attached to an old computer in a dark room: and this visual and sonic ambience surrounding the text is crucial to the experience, delivering the shocks and surprises so the text adventure itself doesn't need to.
This forms chapter 1 of "Stories Untold", a commercial compilation of four spooky adventures, and it sets the creepy tone very well. This chapter can be downloaded for free from Steam and GOG.
