I think Kerni's next game should have some aspect of forced master again. I really liked that in the previous game and I feel like without it, it sort of limits the natural progression of the game. It sort of feels a bit like there's no real driving force to the plot outside of the initial discovery of the addictive body fluids. After that it sort of just goes, girls on outside keeps getting teased that they should join the group, group decides to move +1 on the kinkometer because they want to get more pleasure. It just sort of makes the game feel a bit like it moves forward because it's a porn game and you need to get kinkier as the game moves forward. Maybe I'd feel different if there was a play by play commentary about how the vaccine is continually changing them, so they are growing more needy, they need chastity in order not to tackle MC constantly, what will the changes demand next?! But at this point the test nature feels less like a trap/problem and more like another sex toy, there so that the girl's horniness makes sense, like they're always wearing vibrators. There's no, oh no, we might be in danger, aspect. It feels like, huh that's strange, guess we have to form a harem now to research it. There's just no real drive to the plot.
Back when this game was first announced, I thought that the driving force would be the pirate base. That maybe they'd need to enter for resources in story and they'd encounter something that drives them to greater sensual heights. But outside of gathering resources and a few toys, I don't really understand what the pirate base is supposed to do... When you entered a new section of the space station, you always wondered what test the base would throw at them. But this just sort of feels like a tacked on thing that doesn't really drive the story. With the cheat, you can actually completely avoid it, never entering it, and as a person who knows how much work went into it, that absolutely sucks.
I also think resources sort of sucks the fun out of the game. I'd like for that not to return in the next game.
