A lot of early jump & run games worked on a screen-by-screen basis (Prince of Persia, Lode Runner, etc) rather than actually having smooth, NES-style scrolling.

In any case, this Wikipedia article [1] backs up that the only real predecessors of Keen on PC were early-80s console ports that were extremely limited in other ways, like having boxy, low color count graphics.

- AtlasBarfed 5y agoseadragon on the apple II did scrolling, as did a lot of shmup and shmup ports. I've never written a side scroller so I don't know how much of the gravity/platform mechanic complicates the scrolling, but I imagine it's about the same thing as shmups with hitboxes, sprites, etc.
