Funnily I saw the playthrough of your game in YouTube and it really looks like a labour of love. As the guy who did the playthrough suggested, still need to buy it as a thank you.
Or is that another game with a red button? The maker of the game I'm thinking about wrote a comment on YouTube
After driving my current car with Android Automotive for over 45.000 km I can only advice to stay away from vehicles using it
Android Auto (with the car working as a display for your phone) is really nice. AA OS is not.
