I liked this one. A bit wacky, but the different physics when the water kicks in and then space... very nice indeed. the feel of space was super with the momentum and lack of friction. Fun wee game... The sound effects on the balance parcel got me... I wasn't sold on that part to be fair, but you could really mix it up with some more minigames.
I think having to repair your vehicle and upgrades (bigger van, or package shrinking ray) would def fit. My brain also thought of a delivery drone for some reason when I was playing this too... That'd certainly fit the game as well.
Great game jam project - well done!
