My name is Luzia...and this story isn't about me, but my sister.


Luzia is a typical eight year...*Cough, a 12-year-old girl with a very sarcastic and playful attitude. Her story takes place on an unfortunate night where everything she has ever known, takes a turn for the worst. Her older sister Sombria has suffered an adverse fate as she and Luzia try to return "Home". Is she a ghost, a guardian, a walking corpse or still alive? Oh! I've said too much...or have I?


The game uses an RPG top-down style which consists of finding items, secrets and solving puzzles to progress the story. The game progresses in chapters which are filled with secrets and easter eggs! Unlock multiple endings by following clues and your gut!

As of January 1 2024, Steam will officially stop supporting the Windows 7, Windows 8 and Windows 8.1 operating systems. After that date, the Steam Client will no longer run on those versions of Windows. Source: Steam
