I really enjoyed playing this game. Having worked in a warehouse environment before, I think you captured many of the things you need to think about when shipping a package. And you made it pretty fun!
Once I figured out how to play, I found that I really wanted to ship as many orders as possible. I like that there is a "damage" system, but I thought it was a bit challenging to catch some of them, especially the book. Also, there is a typo on the spine of the book that I don't think you're counting as damage.
If you go further with this, I'd perhaps allow the player to place the machines where they see fit. It might also be cool to allow the player to "pick" the items themselves, perhaps from an Amazon Robotics style robot.
All in all, fantastic work. Really polished. Thanks for making it.
