I really enjoy playing you game, but one thing is rly tedeous imo and that is cleaning. I know you can have worker that does it but to get a perfect factory you need 2 handlers, 4 botanists and 4 chemist. I would like for endgame if you could by somekind of automatic cleaning robot or something like that.
I believe it should be endgame and maybe you need to switch the batteries for it or something like that.
Hope the tip finds you well, i'm also a developer by proffessions if you ever need any help or are looking for some people.
