Feedback: I enjoyed the short bit that you have here.
I found the writing to be quite good, and I like the art style you have. Even with the short amount of time all the characters showed distinct, individual personalities and likely some decent depth.
Usually I think the immediate "Oh he's cute, I want to fantasize and/or fuck him" is a bit rushed or even forced, but with the backstory provided, both her extended social isolation and the dad's comments on the pc and Sara's childhood, plus her thoughts during the scene it felt like a natural progression.
Regarding the two Sara scenes: Window - loved it, tickled my voyeurism/exhibitionism fetish quite nicely. The bedroom scene - Hot! An element that I will almost certainly consider a bonus to sexiness is transparent/translucent clothes from moisture, I suspect it hits the aforementioned fetish, so that was quite nice to see as well.
Overall, if the game continues to have this feel as it progresses then I will definitely consider putting some of my (quite small) game budget towards this.
I am curious whether any of the various choices are going to influence the game further down the line, or if they just add a feel of agency to the pc's personality (which I thought was done well).
