Belmont's curse is good, but it's kind of a different beast.

Rose is somewhere in between classic Belmont and "igavania". She has some advanced/traversal moves, but most of the time she's slow, doesn't jump very high and has little air control. Any bad input can be severely punished, and three or four hits are generally enough to kill you.

I do like Igavania but unless you're going into challenge modes like fixed exp level/hard mode, they are never that brutal.

I did have some fun on OoE hard mode though, even trying to get the boss medals (they hit so hard in this mode you kind of need to be almost there anyway).

That's fair. CotM is one of those games where, if you didn't have the walkthrough, it would be a huge pain in the ass to figure out.
