Hi! This game is wonderful and I am excited for the update! Thank you for releasing it. However, I can't get it to work on my Mac computer when downloading the contents for the demo. It just comes in a zipped folder. Do I extract these files and put them in another folder of my existing demo? Do I delete the existing demo that I have saves on so it can work properly or should the new 2.0 demo be another program entirely? Please help whenever you can, if you can--no rush.
