Well, the good news is that this is the end of the demo. All that is left after the dialog after the ship battle is a screenshot of two male characters and one female character, and it loops back to the start screen so you aren't missing much.
I personally was lucky enough to go through the new demo with 0 issues. I'm so looking forward to seeing this game: The gameplay is utterly amazing, the art is nice, and I adore Lynn + Miene (And Ill mentionned a long time ago that there will be a way (though probably difficult) to have an happy ending with the two, which makes me happy

).
To be honest, the demo of this game single-handily got me interested roguelike-turn based combat, it is that good to me. I haven't looked at this thread for some time, because I knew it'd rekindle my crave for this game and make me play the same demo over and over. Maidensnow Eve recently got my #1 "best ever h-game" award, but I can seriously see this game taking that award over.
That said, I agree that the game should only be released when it's 'done'. I don't mind at all if there's things added after release, but the game should be functional at least. Author's decision of course.
