I just bought it and it's pretty nice. I agree with Eben that it's not much of a roguelike, though - it does have permadeath, but its 'character progression' system works through upgrading your family manor, which then gets passed on to your next character, so ultimately there's not much difference from a non-permadeath RPG.
It's definitely fun as a procedural platformer and the character traits are quite nicely done, so I do recommend it.
