AYYYYYY, someone doing it also (I call it Hellcore (sounds cool)) one note on the whole nether ONLY thing - if broken portals could spawn with stone slabs, you would be able to get max enchantments, because you'd be able to disenchant soul speed books and such, but oh well (also, I think it's possible to remove the "recording" thing top right corner (wouldn't know it myself, my PC can't run sodium or anything for 1.20 and can't update because it's BAD))
