Extract the content of the zip into the Grandma's House folder and overwrite.
does that go for the mac app as well? I tried overwriting the files in the .app file but that broke the images for the scenes. I scrolled through the comments here and the instructions i found in a few posts are all with windows examples.
This is where i overwrote the files:
GH.app - show package conetents > "contents > Resources > autorun > game" for the script and gallery_scenes, and then in "... > gui" for the .png files.
If that's the wrong way, what's the right way :D, lookiing through all the positive feedback in the comments makes me wanna play the game, but I'd prefer a complete exp with the patch seeing that it's there.
Thanks
