Thank you for playing Kohana, and I'm happy to hear that it resonates with you!
Personally, I've noticed that the expression of feelings through food is more prominent in Japanese cuisine, such as the dedication of certain foods to welcome specific seasons and the significance attached to certain dishes. I've always loved this concept in storytelling, and especially in Kohana, I aimed to incorporate it into the game.
Food elements are present in all of our visual novels. I hope you'll enjoy the other two as well!
