Thanks - I'm used to doing that and I'm familiar with the message and how to work around it, but this seems to be something different: it says the app is damaged and it's not possible to 'unlock' it from the security menu.
OSX 10.15 no longer has the "anywhere" option, apps need to be signed now by a developer certificate :/ a quick fix is to run the following command in terminal: xattr -r -d com.apple.quarantine <path to file or app>
Dammit Apple :( thanks for the fix. I'm publishing all my games on web from now on, maintaining different OS versions takes so much time and effort, and I can't do that with my resources.
