Wasn't expecting a flying car, but I dig it. And a nice little city landscape you built there!
I would say I would enjoy a "fly faster" button to get around a bit quicker in-between deliveries. Additionally, the compass is super helpful, but after dropping off one of the deliveries, the arrow points back to one I've done already until the package hits the ground. I'd like if there was a way to see where the other locations are at the same time so that I could start flying towards them instead of waiting for the package to hit the ground and then updating my direction.
But neat idea!
