The issue with that is that Zell physically COULDN'T add any of that to FOBS. He had reached the size limits of what he could do with his chosen engine. That's why he's remaking it in a different one.
I know the whole story of why there's A and B, and the whole size limit problem (hence why my game over suggestion was literally just a text box pop-up) I'm saying he should've ended it before that point, it was a complete game with fun mechanics and a sizeable chunk of content, more than most games, long before he needed to split it. Then if he wanted to continue it, sequels, episodes, remakes, new engine, etc.
On a slightly related note, the ... "monster arena" far left of the gallery, I genuinely don't know what the point of it is. "Here's enemies you've fought before, they respawn and you have infinite health so you can't game over", ok, why? He needed space? Remove that then.
