So far this game's got top notch animation work, which gives it an edge over a lot of porn games. I can respect the slow build-up, only time can tell if it will pay off sooner or later.
If the dev is open to advice: focus on getting a character or two all the way through the build-up before adding more girls. It'll get more people invested in following your game early on if they don't feel blueballed by a lack of vaginal, which will pay off in the long run. This especially goes for the titular character. Now I'm not saying rush through the build-up with tsunade, but do keep in mind that you got people to click on this thread with her name.
