l apologize to the developer; for all the games l have played(outside and inside F95 or hentai/normal games), I can't stand lengthy "prologues" with lot of text or slow progress to the main point. Slow skipping also without a toggle is also annoying to say the least.
Of course, the "mode" I go in here is 'scouting". Seeing what the game has, what it allows you to do and what it doesn't. l love player agency so an anal only playthrough(can go anything but vaginal) and having the world and the protagonist react to it, is enough to immerse me; meaningful choices do enhance it.
You can't know everything from the start since it depends how the game is designed. The most memorable example l could find(better not name it) is; at 5 five mins when the game starts, there is someone that wants sex and offers anal only. The heroine considers it and it is up to you to choose have anal or not. That right there shows the player a lot; exactly how certain genius games(Deus Ex 1) right at the start of the game, show the cards; what you can do.
My intention isn't to "oh, l can make a better make" or "this developer doesn't know what he is doing"; merely an opinion, a food for thought. I did learnt a lot for playing all the types of games, from the bad, to good, mediocre to insulting ones(insulting to the player and their time).
If the developer doesn't want this opinion or whatever you want to call it, you can go ahead and delete this.
Take care
