This game is really charming but I agree with the last two posts talking about the MC/rival, I really hope in the future there will be more depth to them so they can blend in. It's really immersion breaking, like bad, but I understand it's probably a lot more difficult to treat the customizable characters the same way as the npcs.
I'm a huge fan of the nose and body selection in this game! Part of me wishes there was a bit more (like maybe eye selection or general face selection), but that might also stem from me only seeing the flat MC/rival. I understand this is also only a demo, but I'm sure you guys are putting in a lot of hard work and love for this game and I want to see more :)
