Thanks a lot for the detailed feedback!
Regarding batch dragging: making it a default feature might break a hidden core mechanic built around "attention management." Single dragging requires player time and focus, which creates that intended pressure. If you could drag everything at once, that pressure mechanism disappears! However, I'm thinking of evolving this idea for future updates — instead of giving batch dragging right away, player could unlock/buy tools that allow for more efficient resource handling.
As for the building plots: at the start of each era, the game actually states which building is available and what buffs/debuffs are active for that era. But I totally agree that adding a UI tooltip/indicator directly on the plot would be way clearer — we just ran out of jam time to implement it!
Glad you saw your progress improve on the second try. Thanks again for playing!
