This looks fun, and I tried to play it on my Mac. I couldn't make it work. This is what I did. I chose download for Mac. When I select the file from the Downloads folder, it just launches the app. I couldn't install it like usual apps for the Mac.(Usual downloads launch an installation process.) Is it supposed to work like that? (I am not using the most recent Mac OS). None of the key controls do anything when I hold the cursor and try to rotate or make changes.I don't know if I am doing something wrong or not.
