Slendrina: The Cellar

This story takes place in the 1900's.

Slendrina is the grandaughter of Granny, and presumably the daughter of Slenderman.

She is a ghost.

You are trapped in her cellar and you must collect 8 books to escape, derived from the Slenderman games.

Slendrina: The Cellar is a first-person horror game that challenges you to try to escape from Slendrina (the female and equally scary version of the mythical Slenderman).

Game was made originally for mobile devices (exclusive to the Google Play Store), but has an official PC Port you can find on Gamejolt.
