I have only the Kitten route, the others was blocked. That is, I was offered a choice without a choice. And to see all three all three routes, I need to play the game again from beginning. Not a good idea. But the game is still a masterpiece.
A strange pretension, considering that each route is clearly determined (you understand what every route is about). All three parts ago you didn’t want your Ashe to be cuckquean or show some dominant side. And now you aren't happy that the game does not allow you to choose something that your Ashe has never demonstrated.
While many people often complain that choices in video games literally change nothing, you're complaining that choices in this VN change something in a too significant way.
And you say "I need to play the game again from the beginning" — as if this isn't a Visual Novel where you can skip through the entire story, but some kind of gameplay grind-fest for tens of hours.
For my playthrough I got the routes I wanted: it's Kitten and Cuckquean, and I don't feel deceived that the game didn't give me the Siren route, because it wouldn't make any sense in case of my playthrough.
