Wait, what? You don't see it in your itch.io collection? Maybe we did something wrong =8| We updated a new 1.47 file, with a different name... maybe that breaks the owning? Doesn't make much sense! We'll figure that out, sorry!
EDIT: UOPS! I uploaded the game with a different file name, and that seems to break the owning, indeed! Do you have, by any chance, the last file you downloaded (the .zip file), so I can set the same name? It was something like "Game + player manual.zip"
