Hah! I’ve had my own grievances about that game. Care to explain?
It feels very compromised to me. It's harder than the other Castleroids, but in a way I cannot describe using any other word besides "rushed", like enemy aggression and behavior does not match how much damage they do, and Shanoa's dodge is very finicky, enough that I just resolved to learn the game such that I never
needed to use it. While they all look GREAT, I'm not the biggest fan of many of the new enemy types. For most of the story, Shanoa is just kind of THERE, only really blooming in the game's second half, and there's little to the game in general that feels like it meaningfully adds to the overall story Iga was already telling for Castlevania.
I think it's compromised between Konami's DESIRES for a Castlevania game versus Iga's genuine need to advance and improve things.
But after playing
Bloodstained: Ritual of the Night, it all really clicked for me. Ecclesia feels MUCH less like Castlevania and MUCH MORE like a prototype for the game that would eventually become Bloodstained. Ritual of the Night reuses much of the artistic and design choices that Ecclesia used, adapts a bunch of the core plot elements, and reuses and improves several of the major gameplay concepts, and it generally has the overall feel of being the game Iga WANTED Ecclesia to be. I wish it had Ecclesia's more fluid and rapid movement and traversal, but who knows, maybe ROTN2 will have that.
So I like Ecclesia more on that basis than as a "Castlevania" game, now that I have a different frame of reference to appreciate it.
