Admittedly, it's a very short now but this is very promising start! You said this is the demo version, when is episode 1 coming out in full?
- The UI looks AMAZEBALLS. I've never seen any developer putting that much effort into the UI, usually it's just the default Ren'py menu. The aesthetic vibe is strong with this one.
- Music matches the vibes. The sound effects are nice too, I love the sound effect where Yuki appears, soo cool!
- The main character is a bit...feminine. Maybe it is just me...Don't get me wrong, he is still goodlooking, and he looks different from all the default Honey Select males.
- When you click on the bios menu, it disappears...is it intended to be so?
- Font is nice and aesthetic, but is a lil' bit hard to see, especially during the first part. The option to change the opacity is pleasant and more games need this!
Overall, I love it and look forward to seeing more of this game. Keep it up!
