The art in this VN is quite charming~ Kristina is very easy on the eyes, certainly, and having different outfits for her on the different routes was a fun little touch, heheh. I also enjoyed the detail where one of the clones in particular was shown to be much more haggard early on, only for us to discover later exactly what the poor thing was having to deal with...
I will say, in addition to wondering about the absent minigame around which the game evidently hinges, I was burning to learn more about the setting and the larger world in which the story is set, you know~? For that matter, while I know Kristina is ultimately more of a self-insert character whose personality shifts around in accordance with the player's choices, I'd love to see her (or perhaps Tulip or even Joanna) get fleshed out some more~ What does she get up to outside of work in this blasted, dystopian world she lives in? What brought her to Nolt'deh, and why does she stay there despite its harsh conditions? That sort of thing, heheheh~
But yes, very nice work~ I'm curious to see how the full version of the game turns out!
