It's pretty good. But overall, it felt like a tiny, teensy bit of a disappointment.
Gameplay: 4/5, Good enough, but pretty easy.
The first section, you can easily one-shot any enemy if you hit their weakpoint. Second section is the same. Third level on, two-shot. Now, I technically grinded since I wanted to see what each girl did, and find each of their weakness, so it might have had an experience. But I fought no more than 5 per level. So, that's saying something.
Also, for the gallery, maybe I'm missing something, but there's no easy way to see animations. Also, you don't unlock all scenes from beating the game, you have to lose to each monster individually (I think. I beat the game, Paralouge too, but no "lose scenes" unlocked). Also, there's no real variation of animations for each enemy, i.e. each monster does one thing. Animations take a while, which I understand, but I still feel a bit disappointed.
Overall, it's an easy game to beat. But the final boss is suddenly way harder than the previous. Still beat it first try... Gallery is slow, and a chore. Also replaying scenes replays the scene. Not one of those, "see the animations" kind of deals.
Visual: 4/5, Mixed Bag.
Several artists worked on the game, and each have their distinct art style. One can even see the variation on the main image and main menu. While I wouldn't say any of them are particularly bad, it's a bit jarring to see such variation. And Ohm is a literal flesh monster girl which kind of scares me, personally.
Again, as I always say in this department, it's all subjective. The environments are really good, and the art overall is also really good. But there's a variety of art styles which is mildly jarring, and some monster girls are of a slightly lower quality.
Also, 90% of all girls are well-endowed. They're all curvy. Some may be short. Some are tiny fairies. But basically, most are curvy monster girls.
Audio: 5/5, いいよー
Each girl has their own voices. There's lewd sounds. There's footsteps, music, and whatever. While the music is average, the lewd sounds are pretty nice, and the voices are great.
Though, I sort of feel as though the VAs were a bit awkward.
Story: 5/5, Undertale, Hentai Edition (Really, it's 3/5).
Basically, you fall into a trap, and fall into a zone where monster girls want to collect mana, and you just want to escape, and through a journal find that their weakness is sex too. So, you fight with your platinum dong.
While it has some sort of nice background and depth to it (which you sort of learn later on) it's nothing... Great. It's not a deep story, it's not overly intriguing. It gets it's job done and generally makes sense. It sort of follows the MGE kind of world so...
Not bad, but pretty standard.
Overall: 4/5, Minor Issues, but Pretty Hot Overall.
The game is easy, so anyone who wants to blaze through can. It's also easy to lose, so those who want to lose, can. I still have some gripes with story, some gripes with gameplay, some gripes with visual. But in the end, those are all minor problems, and
This game is definitely worth playing. It's about an hour long if you just play it. Longer for sure, if you want to 100% it yourself.
