If the video doesn't work try the following:
- Open Terminal.app
- Navigate to the folder containing my game and use the "cd path_to_the_app_folder" command, e.g. "cd ~/Downloads/" if it is in the Downloads folder
- Run the command xattr -dr com.apple.quarantine "Roll Of The Dice.app" (including quotation marks and .app extension)
