Ideas for a Cave Story 2?

I've considered making the 8,934,906th Cave Story comic book that centers around the game's aftermath. I have a couple of ideas about the Demon Crown's lore and what happened to it after Ballos was defeated, but that's about where my imagination ends.

Anyone got anything?

 

Here's an underrated suggestion, don't make a sequel idea based on the third ending, cuz there's absolutely nothing to go off of. Things are way more open after the second ending (with or without mimiga mask), and since events relating to the third ending are canon to the game anyway, elements from that story route can be introduced in a whole other direction.
