Thanks for the feedback! We'll look into the problem ASAP. Could you, please, send us your mac model and OS version? The things is, we've tried it on several macs from 2012 to 2021 but we don't have all of them :)
Drake in a Lake, we've tested our game on the same mac with the same macOS and we've also had an issue, which can be easily fixed. Try the following steps:
1. Start the game
2. Wait for the blackscreen
3. Press and hold CMD ⌘ button and press TAB once
4. Keep holding CMD ⌘ button
5. You'll see a list of apps running on your mac
6. Find a pop up message asking for some permissions for the game
7. Click TAB several times until the frame stops on that pop up message
8. Release CMD ⌘ button
9. Now you should see the pop up message
10. Click on YES (ALLOW) button
11. Use CMD ⌘ + TAB to get back to the game
12. If it doesn't continue right away, please, press CMD ⌘ + Q
13. When the game quits, start it once again
That should do the trick! Hope, it helps :)
