About this game
WELCOME TO SPECTRE OS.
After Stella finally gets an old OS working, she drags you along on this ancient system to spend the week with her and see how capable it is. Despite her enthusiasm though, something seems... not right. Your memories are a bit hazy and you can't exactly seem to remember all too much about your connection with Stella but that's fine! She'll happily remind you.
Explore a fully in-depth OS built from the ground up, with various minigames, secrets and puzzles to uncover.
Delve into a fully 3D world created just for you <3
Unravel the secrets behind your existence and your relationship with Stella
Mess around .... just... not too much....
And make sure you don't go anywhere!
