but in this case, cBob the author came up with the idea of creating FET, and hired an artist, which is Marty, who about now does the add-to on the existing [completed, with benefits] because he wants to. cBob in this case isnt' hired or working for anyone else. he's kind of the boss.
this setting is a more or less "by definition" thing when they started, it's a 2 people team in which over time, i think pretty soon during maybe the first half year working on FET, the border between "boss" writer/coder and "hired" artist disappeared. they clicked. they didn't consider to hire additional help, even when they got stuck really bad. rather they paused their source of income, patreon, when they couldn't deliver in time.
i've seen other on patreon, who went on a milking spree for a mere one liner once a week. long story, and one of the reasons why i don't put money there.
if this game ever hits the stores, i want that. as a hardcopy, to have it in my collection.
p.s. i'm not sure if their next one will match this. could well be one reason why they're hesitant to make up their minds.
