I just played the update and wanted to give some feedback. I don't know if this is a joke because something like Romance sounds really vanilla and not a kink. I can't imagine why a Flat Chest would upset someone unless it is tied into the trap or loli in which case avoiding them would do the same thing but I guess better safe than sorry. The rest are definitely fetishes that some people might want to avoid.
Avoidable is an inaccurate and confusing term which is generally not used here. It should be either optional or skippable. Optional and skippable are two entirely different things and the difference is really important to many people. If it is optional then your choice makes it never happen and if you skip it then it still happened but the MC didn't see it and the player knows it still happened. This will still upset some players if they don't like that kink. If you are really trying to broaden your base then be clear which one you are doing and fix your game appropriately. I personally will not play a game that skips instead of making things optional.
I've paid attention at every scene that had "skip" in it. What you are telling people by saying "skip" is that it still happens. It looks like choosing "skip" just takes you to the end of the scene. If some cases it is written well enough that you don't notice and it seems like it was optional but in others it looks really wonky and strange. In those cases it is better to have a few more renders and/or different dialog as a bridge to make it feel natural. The common way is to create two different paths so that it feels like your choice actually made a difference. I am guessing that doing the way you have been is to save making additional renders but it really doesn't work that well.
It is obvious that you are not a native English speaker. The most glaring and repeated mistake is calling the head of the school the "Manager". A school could is run by a Principal, Dean or Headmaster (Headmistress in this case). There are a few other titles out there but definitely not a "Manager". Maybe it has a different meaning in your country. Also, even though the translation is understandable, if you are trying to appeal to an English speaking audience then you should get a native English speaker to make a large amount of corrections. It would add greatly to the appeal of your game.
I am enjoying your game even though the premise is absurd because you have written it in a way that is consistent and therefore plausible in the world you have created. If you clean it up I would consider subbing to you because it looks like it has a lot of potential and could be fun to play. As it stands now I can't take it seriously enough to put my money into it.
