I am not sure if this was brought up earlier, but I suppose such behaviour is unintended:
While there is some slow arousal growth during any sex scenes, there is no such increase in case you skip said scene. This makes some builds based on arousal useless, unless you spend some time on watching all of triggered scenes. It becomes more obvious at the second part of the game, where most of the scenes are already seen and you just have to collect specific ingredients in large quantities. Most of this runs will consist of up to 80% player waiting for the scene to end (since skipping it will cause lost in potential arousal buildup), and only 20% of actually playing the game.
I really like this game and this is the only inconvenience I've encountered yet.
It is actually on purpose that the arousal keeps increasing when watching an animation. My intention was to give a little benefit to the player for enjoying the scenes, else they might just skip any scene and take away the hentai part of the game.
I mean technically this decision belongs to the player anyway, but I noticed that I skip scenes myself way to often in hentai games, which makes me sad, cause I'd really like to see the spicy stuff, but my pro gamer brain says I should stay time efficient, lol.
It's
just enough to make it
at least a little useful by gaining some extra human essence from Sonja over time.
At least this was my approach of how to deal with players (like myself), who tend to min/max the fun (and in this case: the hentai) out of a game
