As mentioned above I would suggest to split the game into 2 separate games, one for the school part and one for the university part. So far chapter 1 uses the corruption game mechanic with m2f transformation if corruption goes up unchecked, so that the mc frequently has to visit the church to reduce corruption. This mechanic is completely absent in chapter 2, the church and the cult were removed, etc. Most of the NPCs were not carried over. All locations are new. The story seems to take place maybe 1 year after the first chapter. etc. Imho these fundamental changes justify 2 games ...
Chapter 1 has a lot of potential to polish and add more events.
A major point is the energy system. The game simplifies physical energy (work, walking), mental focus (school, social interaction) and sexual energy (sex) as one type of energy. The mc sleeps 8 hours and restores up to 100 Energy (or 12.5 Energy per hour). On the other side 6 hours of school (class or gym) cost 50 Energy (or 8.3 Energy per hour). This leaves only 50 Energy per day for further activities. A "nap" mechanic and meals to restore part of the spent Energy is missing. Once the mc runs out of Energy, he is teleported home, which may lead to missed special events, eg at the weekend.
Energy costs of other activities are somehow out of scale. A small view on Vivian in the morning costs 5 minutes and 5 Energy compared to 8.3 Energy for a full hour at school. Repeating the view on Vivian 12 times results in a cost of 60 Energy for 1 hour which is more than 7 times the rate for school. Many simple talk-actions cost 5 Energy, watching TV costs 10 Energy, going to the theater with Charlotte costs around 50 Energy for 3 hours if the mc corrupts her.
One day mc woke up (100 Energy), got a blow job from Vivian (-10 Energy), went to school (-50 Energy), went to Sheldon where he had sex with Cindy and was around 0 Energy afterwards in the late afternoon.
Sex encounters often sum up Energy costs of 30 Energy for a few minutes due to various walk and talk costs.
One of the reasons why the game is playable is that many actions at home work even if the mc has no energy left, so the mc can have sex, watch porn, etc without energy costs if energy is already at zero. (Just have an eye on the corruption.)
I think that the game would profit from removing energy costs from most talks and peek actions, simply because costs would not fit the selected scale. Other Energy costs should be rescaled.
The sexual activity of mc is already limited by the amount of corruption that can be reduced per day by the priest which is 100 corruption or ca 3-4 orgasms. At start the mc can not have more than 2-3 orgasms per day if he wants to keep corruption low and keep his dick. A limitation of sex per day by corruption and energy is redundant.
Lust should be a major stat for sexual activities but it is not in this game. If Lust reaches 100 there is the chance for spontaneus sex with the Demon which may result in additional corruption. Most sexual encounters however work if the mc has 0 Lust and afterwards he has also 0 Lust. Watching porn results in an immediate orgasm reducing Lust to 0, no way to edge and build up some Lust. Peeking on (naked) females does not increase Lust except for the free +15 Lust once a day when checking the Gym. Other games often require a minimum of Lust to engage in sexual activities.
There are a lot of NPCs introduced but somehow the world stays small. After the first 2 weeks one would expect to have a lot of houses to visit all the school friends and their moms after school, but social interactions are limited mostly to a weekly cycle with one NPC per weekday to visit. This turns the sandbox more into a linear visual novel.
I had great hopes for Kara and Chloe, there are events at a nightclub, etc, but many of these events are not repeatable. At the end of chapter 1 Chloe was enslaved but she still locked the door when taking a shower at home or when she was in her room in the evening. While Kara had a lot of sexual encounters with mc, he never learned where she lives nor got her number. She is probably on the same school, but mc never met her there ...
This world has a lot of potential to become a huge open world ... so don't skip this by just moving forward to a new game. Add more everyday events and some repeatable special events for the NPCs to add life.
Some of the content of chapter 3, the infiltration of the Crusade, could probably be used to add more content to the church in chapter 1, eg let the mc join a weekend event at a monastery to learn more about the church and crusade, have lewd encounters with nuns including femdom, lesbian and BDSM scenes, etc.
