Does not work on Mac! It says the app is damaged!
Pasting from description :)
MacOS Users: please be aware of a feature called Gatekeeper, which may show the message "This application is damaged and can't be opened. You should move it to the trash" when opening Project Kat. You can find information on how to bypass this error in this video. Alternatively, you can try to install Project Kat using the Itch App.
