I downloaded "unrar" in order to be able to unpack the game, and unpacked it like so:
"unrar x chloe-mac64.rar"
This created two folders ("mac64" and "chloe-mac64"), each containing a game calle "Chloe" (but with different icons).
When I tried to run either, I get an error message saying "The application 'Chloe' can't be opened." with no other detail.
Going to the security preferences to allow the app to run didn't do anything (it's not even there)
For what it's worth, this is on an M2 Macbook Air running MacOS 12.7.2
What can I do to run the game?
