And a partial answer to this, my memory being jogged by the linked article's mention of Autodesk Animator (which I spent a lot of time with as a kid), is that Autodesk Animator includes a font SIXBYSIX.FNT appears identical to the Atari's 6x6 ROM font, to the extent I can find examples to compare. Ignoring the riddle of this or that Amiga game, this is a perfect link between VGA-era DOS games, for which I'm sure Animator (Pro) was often used for art, and the Atari ST, because Autodesk Animator is a direct descendant of the program Cyber Paint on the Atari ST (another program I spent a lot of time with as a kid), both programmed by Jim Kent. It's perfectly possible that one of the ST ROM fonts hitchhiked along in the conversion from ST to PC and started cropping up in PC games.
