I too still like the premise and the mood a lot, and it's still a game that I'd like to make. However, in terms of genre and gameplay, it would probably be even more risky than Rose Seed Replica was, so it'll have to wait until I'm better off financially.
Edit: Oh, and it's actually a bit more than the intro text too, but so far I have only ever heard of one player who played it long enough to find the upgrades and see the extra bits of dialogue. But, yeah, it's still not much more than the intro, I guess.
