Great game with a lot of potential.
However many of the classmates breasts are at good sizes and you get several different ones, they are good out of the box.
I personally gets turned off at gigantic breasts, so growing their breasts massively and quickly, makes issues for me in the long run, like a turn off.
I got nothing against large breasts, but gigantic like what Kammys becomes, is not attractive.
I don't believe that any woman or even a man would find it attractive with a girl having so large breasts that she can't move, which the story implies.
Different bodies, look more attractive with the right breast size or a few alternatives.
And massively large and wide asses, turns me off even more.
A good idea is slow growing breasts per time, to allow for more sex play and different scenarios, like for Kammy and her becoming forceful, in different possible ways as she clearly loves the MC.
I'm fine with girls growing larger, like Jaine and her muscles are somewhat fine too, but don't turn her into a man build.
The two twins might look like a cool/nerdy thing. but they just turn you off.
A good idea is for the MC's power to instead just make them stronger and if or when (possible idea of the story) he gets raped, a lot of women starts raping/vore others in turn and especially his friends and classmates, they in turn have to rape or have sex with the MC. You could both make and female domination paths, depending om former choices, also sexual craving for women, like addiction and violence if left alone for too long, like that they need the sperm for some reason.
Humiliation with a weak MC, that women dominate on trains, parks, pet play (and the opposite).
Reason could be blackmail, like threatening with reporting him and having him sent to a male facility (could become a class tour as well, where Miranda points out that the MC really belongs there in a pen, possible with Jaine joining in and having the MC get the experience, while the others continue the tour or if it lasts for a few days (logically before the lab)), (creates a good introduction for blackmail). Vore could be introduced here, where the MC is feed breast milk to grow up again, which could
Making women stronger without growing, should be an option and if the women don't get the result they want, then the could be more forceful and violent. The opposite could be true too, that the MC makes the choice and make them accept his taste.
They could also join the research to make the MC more durable for sex, like coming several times in a row or day.
The super-large dick in small bodies, isn't that attractive.
A large dick is fine, however, too large and the women doesn't look attractive.
The story needs a slower phase with growing, a possibility that voring the MC is slower (or pleasurable to keep inside and possible not as effective when done quickly).
The regrowth of the MC and others could take time and allow for a wide range of scenarios (like used like a masturbation tool or kept inside of a vagina like for bullying or sex play).
Vore could be slower, like the woman walking around and digesting the victims, in some places like normal and barely visible, where few notices and voring the MC and the woman walking in front of his friends. or the opposite, in front of the MC. A woman or classmates, possible new ones or from other classes could also eject the MC or woman and inject or hand the victim over to another bully.
The MC/woman, could travel in panties and be forced into some, where he got to escape at the right moment and seek milk or a friend to get back to the lab, in panties as a domination part of the girl, or possible inside the vagina or mouth. A scenario where a woman wears a sort of a chasity belt could be introduced that's keept while urinating, with holes too small to escape from, which gets cleaned with water etc, a lot of possibilities exist, which also needs some ways of escaping, like gym or pool.
could be locked in a cage by his friends, so none takes him before getting to the lab.
Just going to the nurse, could be too short.
It looks like it's meant to be a lot of activity for the MC, due to the free-move, but the women get super-large right away, like breasts, which require a lot of new girls constantly (horrible story-building).
If the creator is attracted to super-breasts and super-asses, then I advice options to allow for smaller growth or none at all, to expand the player base.
Also add lesbian sex with the MC involved too, like that males/futas can't get married and the marriage can be with another women, ot in case of the male version, forcible dressed like a girl. A skirt could also be used to hide his dick, so he could get a new style as a male in some situations, if it can't shrink soon enough as an example.
