I'm a sucker for a hot man in a speedo, so I was definitely drawn to this u.u
This is definitely a fantastic first-effort. For a new dev, you definitely picked up RenPy quickly, that's something to be proud of!
The character dialogue felt organic and I really got a sense of the character's personalities through their speech quirks. Great job with that!
The story structure could have used some work (feel free to DM me if you want specific details, I'll be happy to share my thoughts). I also felt like the story ended a bit abruptly (I wanted to know what happened on the date 😭). That said, it's understandable since the scope of the game jam only gave us a month to make these stories.
All-in-all, I'd love to see what kind of work you put out in the future since I know we'll only see improvement from here :3.
