Story-wise, this game is one of the best on this site, I am a fan of fictional novels, specially the Japanese/Korean LN/WN, and I can tell the story writer of this game is a LN/WN fan himself cause I get the same vibes as reading a power fantasy novel when playing this game. Ever read Overgeared?
Anyway... there is nothing wrong with the story and more devs should do what the devs of this game are doing with the story. Even without those little adult scenes, which can be counted in one hand, this game is good. But my concern is not about the story. It's the lack of variety. Let me explain why I didn't give this game a perfect score.
First of all, This game is pretty much a linear game. There is not much choices other that the ones where it increases RP if you chose the positive choices, and the choices to continue or discontinue relations with different LIs. Other that that, there's nothing too serious to choose which can affect the overall story; at-least, not till now.
Secondly, there is not much adult scenes when comparing the amount of gameplay there is. Considering this site is mainly based on adult games, this game is nothing special in my opinion in that field. There are other games with the same level of interesting story as this one but with way more scenes that this game has. Also there is not much of a control in the players hand about how the scene is going to be played out (except one or two). Considering the main focus of the game being a fantasy adventure VN I can understand the lack of interest in the variations of adult scenes, but I can just go to steam and play some good games there if that was my intention. Here on this site, My first requirement is some good 18+ stuff which I can properly enjoy with the story.
Thirdly, when I said this game lack variation, what I meant most importantly is how little the player can affect the MC. The MC has a preset personality and the game is to be played with that. There is no REAL choice of how you want the MC to behave towards Female LIs, I mean you do have choices, but the choices are just there to gain some rp if you choose the right option or vice versa. Either you agree with the LIs shenanigans to earn a relation point, or you don't and the relationship doesn't advance. There are other games which have choices which can determine the MCs personality, you can either play the saint, the devil, or something in-between, but this one is a set path which you need to follow exactly to advance. I enjoy letting girls walk all over me sometimes, but I don't enjoy the lack of choices and being forced to behave in an exact way without having any alternatives.
Maybe if in the future, the devs let the player decide how they want to play, I would change my opinion about this game but right now, this game in not up there to my liking.
