I spent a long time on this game and really enjoyed it, it is possibly one of my favourite games in this jam ^^ I think you've hit the theme perfectly and most importantly you made a fun game with a clear direction and goal.
From the comments, I'm gathering that you might return to this project and update it? (Please do!) If that is the case, I think the fuel shortage was possibly too painful, so it might be an idea to work on that.
This game was a wonderful achievement, well done, especially as a one person project on a very short game jam!
