It was a very enjoyable experience, I found the air controls a bit janky and encountered a small issue where you could not pick up a package after losing it because it spawned to close to the NPC so the speaking input would show instead of the picking-up. One small improvement would be to make it easier to find the packages before delivery. I found it kind of hard to see where the customers were.
Other than that, it was really fun, cute little game :D Keep it up!
