ok, so I downloaded Cabin Corpse v0.5.61 Mac but it says file is damage and can't be opened.
Not sure why it didn't work, but I've updated the link for Mac. Try the 0.5.63 link
same situation, "can't be opened" , when I compare demo version with Cabin Corpse v0.5.63 Mac everything is the same except for one file on ../ content/MacOs/Cabin Corpse VN there is a question mark instead of icon
