I played through scenario 1, and thought it was really painful. Which imo as it should be, but why not code a factorio mod with this functionality? I think it would be even more fun, and less of a UX/UI hassle?
Seems like a fun idea, definitely doesn’t play nice with safari on iPhone, every click and drag is a viewport scroll event which is pretty unplayable. I’ll check it out again later when I’m on a real computer.
