Hello Rslonik!
I'm very sorry for this super late reply. I just noticed you had commented here!
It may be due to the version. The current build works for sure for MacOS 10.14.
Unfortunately I don't have a Mac to test the game, but I'd assume that the problem starts from 10.15 onward.
Again, I'm very sorry for the late reply! I try to reply to everybody but I forgot there may be comments here . I really thank you for checking the game out and I hope there'll be a solution soon so that you can try out the new version :)
Have a nice day,
Ric
