Let me ask you somethings. If an artist says the sky is yellow despite it being blue, is it yellow? If a chef heats water to 40 degrees below boiling point but says it's boiling, is it boiling? If a game developer doesn't complete a game but says it's finished, is it complete? The answer to all three of these questions is no, with the latter applying to Knightly Passions.
If I was someone who donated to these devs for the game's development, or perhaps even followed this game for the last 4 years of development, I'd be pissed and would probably hit this with a 1 star rating. Thankfully for me, I wasn't. The game is a genuine 3.5/5 but we can't give half stars so I'm giving it a 4 because it's overall enjoyable, but my God does the game have some issues. Listen, this game has 90 reviews and is sitting at a 4 star rating, it's worth playing if you dig the art from the previews. I'm going to use this review to point out my main detractors instead of positives, which I believe might be universally shared opinions. This review contains spoilers.
tl;dr: This "completed" game feels like a prelude to an actual game. It feels like a free demo with the purpose of getting you hooked to buy the actual game, however it is the actual game. Everything in it feels like the beginning of something better, however nothing ever gets to that better part before it all abruptly ends. I was genuinely interested in the story and the characters. I was having fun with the honestly mediocre gameplay and minigames. I love the art style and point & click layout. So when I hit the credits scene as well as anytime I unlocked all of a girl's scenes I just felt confused, unsatisfied, and disappointed. Thinking to myself, "that's it?" Where's the rest of it?" It's called Knightly Passions, but I don't feel any of the passion.
Gameplay
The problem is that you have a deck builder in which you can't actually build a deck. The quest system, the minigames, and the quick time events are all fun and the crafting actually serves a purpose, but since the core gameplay (the combat) is inherently flawed the gameplay itself takes a massive hit.
The Main Story
The main story is less important than the side stories. In no media should this ever be the case. You don't progress the main story at a reasonable rate with notable plot moments, aside from the beginning and end. The major side stories (I'd consider there to be three of them - the Elf, the Nuns, and the Wolf/Vampire) are great, but that doesn't excuse this issue. The main story is also framed in the lore as though it is time-crucial, but the pacing says otherwise. This is a story-heavy game, the main story needed to be executed well and it wasn't. The DLCs also have continuity issues, however I'm not too certain on if they're supposed to even be canon or not. For some reason in the Christmas one, the drunk is aware yet unconcerned that you're sheltering an elf (a major plot point in her storyline) and the Arms Trader knows the elf well enough to either agree to a threesome with her or get close enough to be captured by the elf and agree to a threesome. It's hot as hell and leads to what might possibly be the best h-scene in this game, but it's still random. In the Halloween one the townsfolk switch from acting like they just met you to acting like they've known you for months. It's confusing. All that aside, the most egregious issue with this game is that the story ends on a cliffhanger that was put in place in order to sell the promise of a sequel. Not only that, but the Elf and Nun side stories are also incomplete, with the Elf's cliffhanger feeding into the main story's cliffhanger and the Nun's being up in the air, hell it's practically forgotten. Right when you feel as though the main story is about to actually progress somewhere, it ends on a cliffhanger. My God, it's ridiculous. This doesn't feel like a full game, it feels like a prelude to the real game. You'll be 3 hours in and have gotten nowhere with the main story only for it to half-assed "conclude."
Character Development
This bothers me more than the main story issue, since the game is called Knightly Passions yet there is barely any passion. You develop these romantic and sexual storylines with these girls, but once that storyline is finished all romance dies. There's no miscellaneous romantic dialogue, only two girls have repeatable sex scenes, and for some girls their character story and sexual relationship ends before it really gets anywhere. For example, with the blonde nun you have six sexual encounters with her without any meaningful dialogue between the two of you. Then her story twist occurs, the two of you barely talk about it, then her story ends. The Halloween DLC, which focuses on her, doesn't even do anything to mend this issue. In fact, it kind of enhances it. Here's another example: the Maidservant is clearly head over heels with MC and you start building a budding relationship with her. Then, you randomly drunkingly rail her and there is no dialogue afterwards, it's as if it never occurred. Her story then ends right there. This isn't a dating sim, by you need to have some meaningful and permanent character development between MC and his harem and have it reflected in the game.
Hentai
There is no sex scene with the vampire. She plays a prominent role in the game, more so than some of the other girls, yet she has no sex scene or any exploration of her character. She has a title-screen still image, but that's it. The one DLC adds a still frame of her naked like a pin-up girl, but that's incredibly disappointing. There are hints at a story for her that would naturally lead to sex, but there is none. The Blonde Nun has one animated scene of her masturbating and then six "scenes" that are still frames (some good, some bad) and no meaningful dialogue. Until the DLC (which does not excuse the base-game issue), she is the only girl in the harem who does not have a proper animated sex scene (aside from the vampire). The Maidservant's and Governor's wife's scenes feel quite random, almost shoehorned in. The effort for their scenes could've been given to the Redhead Nun and Blonde Nun respectively, as the former lacks a proper amount of scenes for how long her story is and the latter lacks a proper animated sex scene (until the DLC). The Witch, who is the most important girl in the story, doesn't have a proper "normal" sex scene with MC. That feels wrong. Her scenes are great, but she lacks the most crucial scene of all. It doesn't help that the quality set by the Arms Dealer, Elf, and Black-haired Nun scenes (which are fantastic) sets the bar so high that all other girl's scenes are negatively impacted as a result.
The Mermaid Issue
The game confirms mermaids existing in the game via a quest, there are mermaids drawn on the map, there is a specific mermaid item for crafting, and there is an unused jpeg of a female mermaid. The dev straight up did not include any mermaids in the "complete" game but left all commentary towards mermaids in. It's misleading. If someone on a forum doesn't tell you they're absent, you'd spend a lot of time looking for them as the game clearly indicates they're a real thing that you can and should seek out.
I want to say so much more, but I'm already saying a lot and this review has gone on for far too long. You get the picture.
