no problem : ) And yea, going to update the game for Catalina soon. So it might work on everything. I saw that games like "A Short Hike" made 2 versions for Mac. Just Mac and Mac Catalina. So yea, that's how weird the Catalina update is I guess XD
ah I see, there is a problem, again, not sure if I can fix it from my end but on the last devlog, "Gustavo" put a helping video in his comment how to fix it.
Read my comment in the file thread. You have to grant execution permission to the executable file inside the package using Terminal, for some reason, the file lost the 'x' attribute that make it a real application.
