Maybe I'm missing something, but not only does Rogue Legacy not seem like a rogue-lite to me (let alone a Rogue-like), it also seems to have a completely broken and unfun design.
The core of the game is permanent progress. When you start off, the game is very hard, but not necessarily in a fun way (meaning if you go to some areas the enemies take an insane number of hits, leading to boredom even if you find a safe method of hitting them). Then it becomes easy when you get permanent upgrades (such as killing enemies in very few hits). The permanent upgrade tree is huge, meaning the game is prepared to offer you a long, boring grind.
You can lock down the castle design if you want. That alone probably disqualifies it. What ends up happening is that you'll find things in the castle that you literally have no way of doing because you don't have the right equips/spells/traits. Usually there is no improvisation or cleverness involved (small holes, you have to be small, enemies behind wall, you need a spell that aims in that direction, no way around it). It's just "you don't have the right stuff, but you can restart, lock it down and come back!" That's terrible design. It is never, ever difficult to get back to the area in question, so it amounts to a pure, boring, needless grind.
Most of the randomization of the character is only for show. Your character is bald, or sees only black and white. These add nothing to the gameplay, provide hardly any real variety, and no basis for improvisation or learning. They just distract from the the fact that the game is a grindathon.
I found the design to be not only awful, but vaguely insulting. Like we're not supposed to realize this is a permanent progress grindathon, with a limited configuration of rooms which you can even lock down if you want, because of the shallow "roguelike" elements. The name of the game itself seems like a marketing trick.
Decent gameplay at times though, ruined by a painfully dischordant game design.
