I'm honestly a bit hurt to give this only three stars. If it was the dev's first work, I'd give it 5. However, there are some things that the dev simply has not improved on.
Story, writing, humor, all that is fantastic. But the dev seems to have spread themselves too thin with the LIs In their last game, there weren't even that many main LIs, and yet there was not much content with any of them. The "standard" based of my experience (so grain of salt and all that) is 8-10 scenes with each main LI, with 1-3 of those scenes being tension building scenes, not full on lewd (spying in showed, shy handjob, etc...)
As of the most recent update, all of the main girls only have 2-3 scenes, with one being a guaranteed skip, as it is just teasing. Given the dev's previous game I was expecting more improvement in this area. A lot of content so far, but yet at the same time barely any content.
Hopefully things pick up in future updates. As I mentioned, each main girl should have about 8-10 scenes each. That's pretty standard. If this is too much, dev might want to tighten up on their next game and have less LIs with more content. 3-4 LIs is pretty standard, with 1-3 side girls who have 1 maybe 2 scenes each.
I really want to give the finished product 4-5 stars, please add more porn to your porn game, or maybe consider just making normal video games, as you seem to do everything else really well.
