Game is adorable! I absolutely love it!
But there is one nasty bug (or as I think it's a bug)
Quarry drops their stones below the surface, and (probably that's connected) real stone income is far from what statistics say.
May I suggest to place animation start for stone at some static point (probably on top of the quarry) instead of squarrymen? Or maybe make a fail-safe feature to move "below-ground" items up until they are pickable?
Right now quarry is kinda wall, and I think that's the reason.
P. S. Played portable windows version.
