I will be following the game progress with great interest. Games like this are so nice when they have soul put into them by their creators. Which this one looks to be!
Only things I'd note in the demo to work on would be having a bigger margin on the left of the textbox, tidying up the dialogue not having capitals when starting a new line (I'm sure this is on your to-do if nothing else haha), and maybe having a bit of a gap in transition between locations to allow the music fade out/in a bit more time so there's less overlap and subsequent dissonance. Thumbs up!
PS: Don't forget to add more petite succubi in addition to the bustier ones!
