It's only kind of a rogue like from what I could tell. It doesn't really have permanent death, though the dungeons are random each time you enter so if you die in one you need to start anew in there.
I just started playing Caves of Qud. It has two modes: rogue mode with perma-death and rpg mode where it saves at a checkpoint you can set. Having both options is nice.
I like this style of game, so I'll definitely be trying Moonring, too.
