Difficulty?

In my experience I either play on easy for a casual play through and hard for the challenge normal isn't a thing I ever touch because it's just not appealing to me for some reason apart from that in a rogue-light difficulty doesn't matter too much to me (he says after beating FTL by just dying twice) to me the only thing I really want is a unlimited mode where my run ends when I get blown up and not when I have cleared out 4 sectors
