I found this confusing. Why does a person walking need both food and fuel? Am I drinking the fuel? Why does using 4 food and 30 food restore the same amount of food, to a maximum of 5 food? Shouldn't using 30 food leave me with 25 food? Seems too difficult to get a working vehicle.
The aesthetic is very cool and the music as atmospheric. It makes me think of a cute Neo Scavenger demake. I hope you'll continue to develop this beyond the game jam.
It was cool to see your design notes in the source too, thank you for sharing.
