I really like the audio in this game, you picked two good songs, and the sound effects fit well! I like the particle effects on the wings and used for the storm as well.
The one trouble I had with this game is the player doesn't have a great point of reference for movement. I was never quite sure how far away or how big a package was and was surprised when I passed it. I think it has a lot to do with the background being a mostly solid color. This could maybe be fixed by having other objects pass as well, or maybe even something of the ground is visible?
Awesome job, especially submitting in two game jams so close together!
