Not going to lie, I've been pretty addicted to building my factory this afternoon. Wish I could save my progress!
The visuals for the stand really set the mood and that ghost model was the perfect level of eerie, and its really satisfying when you start really making the $$$.
Other than saving, if there was one thing I wish it had if there was more time, would be visual differentiation of the machines. I enjoyed building up little sections of the factory for different types of production to make my movement through the factory more efficient, so being able to see the differences between each time would just be the cherry on top.
