I think this is a really solid game idea, that can actually have potential to be a serious game for learning. I played through a week of the game, and quite enjoyed the vibe.
However, I think the game could improved upon in terms of balancing. First off, I didn't really use the isntructions, and just tried to fill in the truck as spacially efficient as possible. And it turned out well every time! I didn't read the labels, didn't look at the map, it was just a very cozy space management game to me.
I think the map and labels is generally a mechanic, that if it'd work as you planned, might've made the game a bit too long to get into. In this regard I'd say there are two ways to improve it: 1. Get rid of the complex elements, and focus more on space management. That would make it more fun, but also rid it of the more serious aspect. 2. Rebalance the complexities of the labels and map, and make it more engaging. I think if you make it not as tedious, but still involve strategizing it can become a truly unique logistics learning experience.
I really enjoyed the game. Great job!
