This game's rather hit or miss for me. It's conceptually in a very strong place. You are a hive mind using your brainwashed peons to corrupt and infect an ensemble of heroines in a trainer-style game as you watch them gradually grow more and more tempted, eventually ending in their complete infestation and transformation as some of your mightiest subordinates.
The game is very good at establishing tone, it makes no bones about the fact that you are in fact the villain, and can put the heroines in very painful sessions of torture and brainwashing. The bonus bad endings help provide further context on the invasion of Earth to sell this narrative.
Unfortunately, whilst this game has the style, it’s lacking a lot in the areas that would make this matter more.
The heroines aren’t very well characterized, and the game takes its sweet time getting them corrupted. Some may have one or two personality traits like with Rose being incredibly cowardly, Trixie trying to play hero, or Eve being a headstrong ass. But it all washes away in the sea of formulaic brainwashing, each heroine follows the same repetitive pattern as anotherdoes in each room you can send them to. Each and every one goes “ooh, this brainwashing actually feels really good!” and start talking like the exact same person when they start breaking down. Their monologuing about the superiority of the infectulons and the weakness of humans in near similar words and tone fit right at home in an 1980’s sci-fi show with villains chewing the scenery like no tomorrow. Even at the fastest conversion rate I felt like I had to skip through scenes since each scene will repeat itself until the character enters a new state of corruption so their dialogue isn't the exact same.
The main combat (which is optional) you can engage in just feels like an afterthought. I was initially excited seeing my unit convert an enemy unit into one of my own, but then when I looked at the enemy and unit profiles I quickly realized that this was a game of rock, paper scissors, but with each unit you have only having an advantage against one specific enemy type. The thing here is that you can’t really take that much advantage off of it as you are only given around eight choices of monster to breed a heroine, everything else you may potentially get randomly if you select your breeder to breed them instead.
Even if you do get a special monster, once more specialized units come in, you might not have much of a chance to use them before they get wiped. With this hamstrung combat system, you’ll likely just send something the strongest monster you have since you have limited control of what you can get to attack the invading humans to get it done and over with.
And for a game that identifies itself as a transformation game, it misses excruciatingly hard with its final transformations. Trixy’s is essentially identical to her penultimate form as an animalistic woman with sharp teeth, just slightly taller and more dark-orange, Absinthe as a mushroom woman and Chieko and a blue alien are covered in bright colours and ugly textures that hurt to look at if you try to concentrate, and Amelia gets an easter egg pattern engraved into her skin as her tits swell large enough to block a doorway. Justine is perhaps the most disappointing case of this. Her penultimate transformation is perhaps one of my favourite states in the game, with her turning sallow, humanoid body lined with reddish brown scales. The next step of evolution to conclude this process is… an identical appearance with the only change being that her head has gone bald because a spider is growing inside of it, big wriggly legs dangling out her newly bulbous head.
W-what? I thought she was supposed to be your psychic? You already have monsters in your army that can already use psychic powers, why does she have something that never uses telekinetic powers mutating out of her cranium? Why do any of what you just did with her head? It’s such a waste of a fun design.
Oh yeah you can also inhabit a body of your own to have sex with your converted heroines, it's pretty damn ugly. Matter of fact, you have even less things you can do with them after you've fully converted them.
It’s a free game, so I recommend at least trying it if you think you’ve the aptitude and tolerance for how it presents its characters, both writing and art. If it seems like you can’t, don’t expect it to break away from what it's doing anytime soon.
