Firstly, the artwork and music seem nice, everything is in proper place. The transition with the music as you change scenery is also a nice touch.
I feel like there is no gameplay at all. The choice of places seem arbitrary so I just went through all the places randomly. I also feel the choices of dialog seem to carry no consequences.
Since you mentioned of expanded dialog choices from 2-3 to 3-4... I don't think this addition matter that much at all. Having only two options but showing different consequences would be much more effective. For now, the different reactions that we get is not enough. Since this is a VN, unlocking different background stories or have branching ending will be a better usage of the dialog options.
Another suggestion from me is to display the question when the player is presented with dialog options. This is just in case if the player go through the dialog pretty fast and didn't get the question.
