TL;DR: Has great potential but still needs some polish.
Honestly, this game has some of the best-written dialogue I've read in a long time. Recently I've been so sick of porn game dialogue that I just skip everything, but this is one of those cases where the writing is surprisingly entertaining. The lines aren't too long but still convey what they're supposed to.
The characters are ALL very endearing and captivating, urging you to keep reading their quirky lines. My favorite is Tara, who is both the most unhinged and most adorable character I've seen in a while (probably ever). I don't know if the author intended for her to be such a psycho from the beginning, but it was definitely effective. There is not a single boring character in this game, and you'll feel like bedding all of them. Not only are they hot and funny, but they also have a surprisingly human side filled with nuances that will make you feel attached.
By all means, this game has the perfect foundation to be one of the best porn games in recent times. I'm not exaggerating.
That being said, the dialogue and characters are where the compliments end.
The game is grindy, and not even in an engaging way. Having to repeat the same actions over and over again just to get money and buy key items is not fun. It would be much more fun if we somehow found some of those items. For example, I don't see why we need to buy a book about slave training when we could conveniently find it in the school's library. We could also acquire things like handcuffs and blindfolds from other characters, like Tara or Ann, in order to use them on Kim and Bonnie. The same thought would apply going forward. Instead of having to buy everything, maybe we could get them in more organic ways, almost like an adventure.
The whole thing where we're blocked from using our fortune is also pretty constraining from a writer's perspective. It could limit your creativity in the future, as you're basically limiting what you can do in order to create a reason for the MC to work.
Another thing that is VERY constraining is the side effects of the rejuv-inator. It raises the stakes, sure, but I don't see a reason to do that in this kind of game. I honestly don't like where the story is going, as it seems like we'll eventually be forced into a life-or-death choice with no in-between. I usually go for the corruption route, but this aspect of the story makes it seem like a love path would basically be a death sentence to the MC. Again, it limits the writer's freedom to write different outcomes. As it stands, this looks like another case of "smut game gone emotional," which can be either very good or very bad.
The characterization of the MC and his goals is also very flawed. In the first "act" we quickly forget our goals and basically become an errand boy for the girls. It's less like we're planning and orchestrating things, and more like we're just going with the flow and being hot. Currently, the game lacks an identity.
First of all, there should be more missions. WAY more missions. Kim Possible is all about getting out of slippery situations and saving the day, but as it stands, this game is just one big fetch quest. There should be moments where we actually help Kim and solve problems instead of getting laid just for being hot. Maybe use our evil mind (or money) in order to create devices that can help us both in and outside of missions. Maybe start our own small business instead of working at a fast food restaurant. Maybe use our contacts in order to privately orchestrate situations that leave Kim in a vulnerable state, only to be saved by us. Seriously, I could give feedback like this all day. There's just so much potential in this game, but that potential is being overwhelmed by mindless grind and constraining narrative decisions.
In my opinion, the entire first part of the game should be reworked, or at least from the part where Kim takes us on the first mission. The sudden shift in tone when we almost die is way too abrupt and leaves a lot do be desired. I don't think we should be forced to either completely love or completely corrupt Kim and the girls. There should be a "loving corruption" path based on how we treat them, basically a give-and-take relationship where we keep them dependent while still giving them love. Also, for those who like love routes, I don't think the love aspect should be so bittersweet. It kind of ruins moments that would otherwise be very cute. Also, Kim's corruption is pretty dry. Instead of corrupting her through lust and depravity, we basically just use her love for us in order to make her do lewd things.
Also, just putting out there, I honestly think it would add extra flavor to the game if all the girls had interactable and romanceable moms. I don't even care if they appear in the canon material. I just think it would add a layer of humanity to the girls while also giving us more milfs and threesome options. Just saying.
Anyway, I'm rambling. In summary:
>Give the MC a more active role in the story
>Remove the narrative limitations
>Rework the first part of the game
>Make the love sweeter and the corruption more depraved
That being said, still a very entertaining game with hot and nuanced moments. Definitely one of a kind. It just needs extra work in certain areas.
