itch.io

idk about that, I used Unzip One to open it 
https://apps.apple.com/us/app/unzip-one-rar-zip-extractor/id1127253508

If you really wanted to download it, click I understand download anyways

Also your game got marked suspicious on Itch.io so it is physically impossible to find this link on dashboard

Mac keeps dining the access saying the application can't be opened instead of no permission
if I am not wrong this happened to all of your game because Together Again seems to have the same issue
But the Unzip Extractor actually helped
This solution took me quite a while to find, do you mind to add this information into the description for every game of yours?
