Finally, a game focused on netori, there are too few on this site. It's probably one of my favorite fetishes so nice to see it getting the love it deserves. And this game delivers on that love. This review is as of v0.3.0, so there are some cons I'll mention that the game dev will hopefully fix or expand on.
Story/Dialog - 5/5
The story is truly the selling point for this game. I would recommend it even if it was a simple VN with nothing else added on to it. The characters all have unique voices and personalities, and it's great to see the way they interact with each other. And the slow but gradual corruption of the main priestess is perfect. I love the demon queen and her mischievous personality. The story and dialog are really great and I would recommend this game for just this. The only complaint I would have is that Vi is supposed to be your partner and the person Mars relies on but there's very little interaction between them.
Gameplay - 3/5
There isn't a lot of gameplay and it's one of the things the dev is going to expand on in the game. The game is structured as a sandbox with a day/evening/night cycle but I don't really see the need for it. The story is linear, and the few side activities you can do are basically pointless. There really needs to be a lot more added to justify the sandbox. The game feels like an empty husk hanging onto a wonderful story.
The only reason I'm not giving the gameplay a 1 or 2 out of 5 is because of the nighttime sex minigame. You have multiple positions and varients to give or receive pleasure and the goal is to provide enough pleasure to break the curse. It's not hard at all and basically works as jerk-off material.
UI/Aesthetics/Music - 2/5
The game looks like a pretty simple renpy game. There's not a lot of polish to it, if you've played another renpy game, this one will look familiar. There is a gallery which I appreciate. The music is good and works well enough for the story, although it's nothing special.
Art/Porn - 5/5
I'm a fan of the art. Looks like an anime but with the artist's own style thrown in there. And the animated scenes during the nighttime minigame are so hot. There are multiple scenes available for both girls during the minigame. I have a hard time deciding which one to watch sometimes, there's so many good ones to choose from.
Overall - 5/5
Obviously, there are some issues with this game. But I'm hoping the dev is going to expand on some of the gameplay issues I talked about. That is really the biggest flaw in this game, but if you're a netori fan like me, you'll love this game. Even if you're not a big netori fan, the corruption of the priestess into doing lewder and lewder things is great as well as the submission of Sera. I would really recommend this game if corruption/maledom are fetishes of yours.
