The twist with Sablan is kinda obvious after you have a meal with him, and it made me think that you could argue that any corruption or bad-ends are sort of his fault for how he tried to motivate her (though based on how most of the scenes go, she's a natural slut who just never had the chance to foster the skill

).
Also, it's sort of funny to me, but Ending 3 definitely seems like the "best/happiest ending". Ending 1 feels like potential sequel-bait and Ending 2 is nice in that she's passing her skills onto the next generation, but Ending 3 feels like she did the most good just by being herself and being a prostitute in the slums (which, thanks to her, are no longer slums). Sort of rare for an H game to make the most perverse of the non-bad ends feel like the best/happiest. I liked it.
There are a couple things I think are sort of wasted potential, though. First, the church. It's a waste you can't go in it and pervy things in holy places are always fun

. Another thing is the guys in the black robes. Aside from letting her be naked in public, they don't really do anything. I thought something was gonna happen with their "goddess", as they mention the room in the back being hers, or possibly the church, since they're right below it. Also, the Harbor could have used a building or two more and definitely should have connected to the center of town. I also half expected to eventually be able to take the ship to that island just south east of the town, but it never happened. Finally, the game could have used some more endings related to specific characters, like one for Mei or Lord Georg or a combination one for if you did both or one for the Farmer Rune's known since childhood or one for the Masseur or working at the tavern (speaking of, too bad she could never be a dancer their) or her black smith friend, etc. That's probably asking a lot, though if I had to pick one, I really wish Mei had gotten an ending. Would have been nice

Given that the creator seems to keep updating the game, I suppose it's possible all that could still happen. Here's hoping!
