Currently this mod is for Forge 1.16 and I'd like to use it in Forge 1.18.2 please.

Like you said in the mod description, this mod rewards exploration rather than relying on an arbitrary obsidian rectangle. And I think that sounds awesome.

If there's anything that is hard to port or that you want to change anyway, that's fine. I just like the idea of Nether Portal spawns being a limited thing at low y-coordinates that the player needs to seek out.
