Hello! I'm having issues with the download (it's not working on my Mac for some reason). I sent an email to your Gmail!
don't know if this is resolved yet but in case it's not, try running this in terminal
chmod +x "/Applications/DominoHouse.app/Contents/MacOS/Domino House"
It worked for me. It gives it executable permissions so it can run, which was the problem for me.
