A horror game putting me in a room with a Furby would be spooky enough for me; those things are terrifying. Force me to care for a Furby while also avoiding the wrath of its bloodthirsty mamabot and no, no thank you, no, that's kind but no, no thank you. You, however, may be interested in Tattletail [Steam page]. It's a first-person horror game set around Christmas 1998, starring a small child playing with the year's hottest toy when bad things happen. It was released a few days after Christmas, fittingly, by a small team including Ben Esposito of Donut County and Arcane Kids fame. Here, watch its old television commercial:
Mate, that's not on.
So, as I understand it, there you are in the house at night with no one to help, playing with your fuzzbuddy while avoiding its murderous having to complete tasks while avoiding a murderous Mama Tattletail. Only, little Tattletail will nag you to groom, feed, and charge it - making noise which might attract Mama. It all looks a bit Slender Man-ish, with the added fun of looking after a daffy baby toy. I don't mean that as dismissively as it may sound.
Tattletail is £3.99/4,99€/$4.99 on Steam for Windows and Mac. It's made by Waygetter Electronics, who are really cartoonist Geneva Hodgson, Wobbledogs dev Tom Astle, and Ben Esposito, also borrowing the voice of Ryann Shannon.
[Disclosure: Ben Esposito has done stuff for Wild Rumpus events, and I was once complicit in the stealing of his property. My fellow criminals and I found some mysterious and ghastly sunglasses/visor combo headwear abandoned in a club after closing and, uh, took it home because it was the worst thing we'd ever seen. Turns out, it was his. Look, I'm not proud of my crimes, but putting that horror on my head was surely punishment enough. I've served my time.]
