Love the game!! Here's some feedback:
I noticed the modules won't output if the bell is not aligned. Was this intentional?
Would also love to have belt splitters, mergers and bridges, for the full experience.
Would it be possible to have blueprints? Also would like the copy function to be used multiple times in a row.
Regarding the area expand, could I have more control on the new rows and columns to insert? It gets bothersome to realign everything to a corner on each upgrade (using selection and moving, obviously).
Would be nice to use rotate and stash directly. Oh, and a flip horizontal/vertical for selections. As complexity grows, the buildings stop being symmetrical, so rotate stops helping.
