Scared Little Ghost: The First Night for the #pico8 on the Lexaloffle BBS.

Or if you have Pico-8, "load #slg"
The uncompressed source is also available as a download in the BBS; for learning only!
And you can still wishlist for when I actually finally finish a retail version of this; probably not in Pico-8 though: https://store.steampowered.com/app/2064550/Scared_Little_Ghost/
