At its core it's a typical "regular girl spirals into sexual degeneracy" RPGM game.
The MC's design and artwork quality is stellar, but the censorship takes a lot away from the scenes. There's also a bit of "staleness" to many of the scenes, especially the interactive ones. Regardless, it's all still hot and the quantity and art quality of scenes makes up for a lot of the issues. The secondary girl has some pretty good scenes and a good design, but unfortunately the game teases showing you the tertiary girl naked (in adult form) but doesn't go through with it - an unnecessary blue-ball. A major highlight is that the dress-up system is fantastic. There's a lot of outfits available (especially for the length of the game) and all of them are customizable in one way or another.
There's a lot of "checklist content." That being: things that seem to only be there to check off a box on the "RPGM requirements" checklist. Easy combat, bare-bones crafting, and meaningless side-quests (to name a few) that are there solely to prolong the game. It's not bad, its just not good. All of this is countered by the story, as its pretty good.
Any logic behind almost all of the sexual content is absent, leading to MC's spiral into sexual degeneracy not being handled well in the slightest. There's times where you'll have no lewd level but she'll act like a full-blown slut. Then there times where you have high lewd level but she'll act shy and nervous. It's odd. I also think the progression of h-scenes shown is strange, such as how you don't unlock a BJ scene until late game (far after she's done more serious sexual stuff). Another example of the logic issue is how you'll enter a scene and choose an option that should lead to something innocent (like masturbation), but it actually leads to something incredibly explicit (such as full-blown rape). Don't get me wrong the h-scenes are hot, they're just seemingly random.
It's nice how the MC isn't opposed to and not hopelessly naïve to sex. What isn't nice is how they handle her virginity. There isn't really a "slow burn" of her venture into sex - the pacing is horrific. To this point I ask: why bother making her a virgin if you're going to throw it away as soon as possible? Something to add, every way for her to lose her virginity is through rape or is in a rape-like way, which sucks. The game also pushes you into having a specific character take her virginity or else you'll miss several h-scenes. Simple games such as this shouldn't require multiple playthroughs for h-content.
I'm focusing on a lot of negatives but to be honest, even with all of them the game is still worth playing if you're looking for a typical RPGM h-game and/or a steampunk RPGM h-game. Three stars is "average," and this game is certainly that. Do I wish MC's design was used for a better game? Yes. Did I have a good time playing despite the flaws? Yes. Should you give it a shot? I believe so.
