Hey there! Thanks for leaving a comment and feedback. I am sorry to disappoint you, but the game will feature very few and far between erotic scenes, probably one every update at most. The game heavily revolves around the story and adding h-scenes where they don't fit purely for the fan-service is something I am not willing to do.
The dialogue being the way it is is a design choice. If you pay attention to each character individually and the narration then you can see that I am capable of writing more elaborately but I choose not to. This will become clearer as to why gradually as the game progresses.
Regarding the patreon question: I am gonna start a patreon when version 0.2 comes around and it will feature a tier that will come to (hopefully) satisfy your fetishes in the way of monthly requests (basically you can ask me to make a scene on demand and I will try my best to make it look good; please keep in mind that I am very new to game development and anything of sorts so don't expect anything breathtaking), since the game itself will mostly feature vanilla stuff.
What I mean by disturb and unease is mainly unsettling scenery and/or sensitive topics. Telling you anything more would spoil the game itself, so apologies for the vague response.
