I loved the arrow gameplay to sort out the different packages according to color. The feeling was really good ; I think I would have loved to always have packages to sort out while I'm arrangeing the cargo.
It took me a few tries to understand that the left cargo was just a "waiting area" and not the shippable one, maybe adding a visual of some kind to make it clearer would have been great.
Nice work on the gamefeel ! Love the sounds of actually shipping a cargo, it gives a real satisfaction to completing a line. And nice animation when turning the pieces ^^
