So much fun. My kids and I really enjoyed it!
By the way, it works fine on macOS via Wine.
Looking forward to the full game someday!
If the OSX version doesn't work for you ("Not found. Obtaining sources.."), here is how to fix it:
1. Download it into your ~/Downloads folder.
2. Open Terminal
3. Type: cd ~/Downloads/LIbraryOfBlabber_016_osx/LIbraryOfBlabber.app/Contents
4. Type: ln -s Data/* .
Now you can double-click it and it should run properly.
