Overall, the gameplay loop is here; so far, you have: a free roam section split in 7 sections, that allow you to either work (spinning a wheel to decide wether you get money or upgrade materials for work and status screen), see the girls on dates with a rival or access the shop (upgrades and chaging the odds of which rival (rich kid or teacher) each girl will serve in the club; and you can also visit the cabaret, where you pick one girl and compete with one of the rivals on who buys the most expensive drink (each drink raises affection and horniness) each round (whoever "wins" gets to interact with the heroine on that round, up to 10 rounds per night), starting a round with 999 horniness means either you or rival can take the girl to the private room (you can't have sex in the demo, from what I've seen; besides horniness, there's also a favorability and money requirement for MC apparently).
So far, I don't really see much of an improvement over the previous games so far. The mistery ntr element apparently only comes into play during the free roam section after you randomly trigger a date event, the quality of the designs, animations and CGs (given the few that can be seen) seem to be about the same as it has been for the last games, but I did somewhat enjoy the techy ambiance and status screen (which, let's be real, is probably not where you want a player's praise to be in this kind of game). While it is a demo, the release date isn't that far, so I don't expect any major changes that could radically change my impression of "game's ok".
