the screens were connected, for example on the first screen, the ants would be connected from the trellises to the big anthill with jam lines and then each of the little anthills around the big one would correspond to tunnels on the top wall in the next layer. then you would connect those tunnels to tubs where you crush the grapes, and then those tubs would be connected again to tunnels on the bottom wall, and those connect to tunnels in the next layer, and so on. and the different colors of jam would add different effects, speeding up different processors, or the ants' speed, stuff like that.
also, i forgot that i wanted to add the tileset to the images since i didn't get most of the processors placeable, if anyone would like to look at those. thank you for your very nice comment! i'll come back for another alchemy jam for sure, so hopefully next time i have something more playable :D
