This was a really cool and polished submission!
I absolutely love management games and this did not disappoint. The only minor complaints that I have are that I had a hard time finding my way into the computer room at the beginning (like others have mentioned) and that I occasionally had my shipments disappear out of thin air. I can see how there might be a robbery mechanic in the game if you don't get your shipments in time, but there was one occasion when a brand new shipment arrived, I was standing right beside the truck, and the shipment immediately vanished before I could pick it up.
Those two issues aside this was fantastic! I found the brief gameplay loop to be addicting and I think that you could have something really special on your hands if you wanted to continue developing it further.
Great job!
(P.S. Also I would have looooooved it if you could stack more than three boxes. Though I understand why you didn't go down that wacky/silly rabbit hole)
