This is a great interpretation of the Famicase design, and the music is ace.
I like that the game is not overly complex with a ton of different resources to manage, individual character stats, and so on. Just a nice chill road trip with friends.
A couple of notes:
1. More variety on the road conditions, such as different types of obstacles, hazards, traffic, weather etc. would be nice to see.
2. It would be great to have a way to earn money, maybe by popping balloons in Chill Mode? On the other hand, running out of cash is basically guaranteed on a real road trip so the game is very realistic in that respect.
Nice work!
