Charna

CHARNA (ЧАРНА) is an atmospheric, exploration, first-person videogame, set in the world of south Slavic mythology. The game also features elements of horror and dark fantasy.

The player assumes control of Charna, a woman who was dragged into
a lake by an unknown entity and then subsequently drowned. However,
after some time had passed, Charna finds herself gasping for air in a
different world, in a different, disfigured body of a sickly, pale woman. At
this point, the player has to uncover the mystery of Charna and is free to
explore this new, twisted world.
