Sadly doesn't seem to work on MacOS.
When I try to open it i just get the message
“ 'Secret Santa Jam 2021' is damaged and can’t be opened. You should move it to the Trash."
I was worried this might be the case, sorry about that. I'll remove the mac version for now. Edit- I did find a possible workaround and made a news post about it so I've reinstated the mac version.
