Error: Couldn't load project data at path ".". Is the .pck file missing? index.js:462
If you've renamed the executable, the associated .pck file should also be renamed to match the executable's name (without the extension).
From the web version.
I just pushed a hotfix. You might've tried it as soon as I was doing it. Does it work for you now?
Good news, it worked. Bad news, I'm addicted help- also the save files is a multi-file jumpscare. Other than that it's a really fun game!
