I finished the first Veteran/ Normal play through last night. I'm currently playing through nightmare.
While I do really think it's a solid game, I can't say I like it as much as say CV3.
Maybe it's just me, but some of the bosses and mid-bosses feel more inspired by Shovel Knight than CV, not that it's a bad thing. It's definitely the closest we've had to a new 8-bit CV.
