This is one of those smut games hamstrung by its own ambition.
I'll give it points for what it does right:
The illustrations are very appealing.
It has a lot of ideas that it wants to dive into.
It caters to a lot of fetishes.
It features a very good Quest Log system.
Unfortunately, it hits a wall when it comes to overcoming its constraints and limitations. The emphasis on the story is extremely high, which is a major issue because despite boasting a full translation, there are times when things are barely better than a MTL. The shaky grasp on English isn't usually a dealbreaker for me with porn games, because most porn games do not try to tell these kinds of stories. Much of the time, the narrative is a conceit for adult content. Not so, here. The just-functional enough prose lands in an uncanny space where I cannot invest in the story, and boy, there is a lot of story.
Next up, is the overly-ambitious, convoluted gameplay. There are layers upon layers of mechanics at work here, and I think they brush up against what's feasible in RPGMaker. Every time I play something that is an "action" RPG in RPGM and requires any sort of twitch controls, it's clunky and barely functional, and Cursed Armor II is no exception.
The progression system requires juggling a lot of routines and actions and stats, and given the janky translation, I was often only barely grasping what I was supposed to be doing and why. I gave up because life is too short to be that invested in a smutty RPG Maker game with pretentions of deep gameplay.
My final verdict is it's a buffet of half-baked ideas. The art assets are nice, but it feels like you're fighting the game's setting, story, lore and gameplay to access them. Give it a pass.
