I just played your demo and I have some questions!
Do you think you'll be able to add pronouns to the MC - considering we're not really "shown" and the name is already custom.
There's a huge line gap in the UI when there's dialogue, personally just me but I found it distracting.
The background art and key images are very different to the sprite models, are you planning on changing to something a little more cohesive. They look like real images of real places/items just blurred.
And lastly are you thinking of adding the game to steam, with achievements, in the future? even if you just added the paid NSFW version - I'd buy it there!
