I love the idea! It's annoying that it's zoomed out so much but I know this is probably a kind of issue that is annoying to fix, especially within a small timeframe. I found a bug where you can press down to get infinite fuel, even if you do not have a package to deliver. Maybe the gas counter should be a meter, rather than just an integer in the corner if this game gets expanded on or revamped. I would give this a 6.5/10. Nice art!
