This game is so good; the art, story and character design. The character design in this game is so cool and colourful. The fact Zu's chest/heart glows when he feels certain emotions is so sweet and a really nice detail to notice. The details! I would recommend just looking at the walkthrough/guide as your choices have an effect on the endings in so many different ways. If you want a happier ending?
This game does go into some more intense subjects, so looking at trigger warnings is a good idea.
The choices are so sweet, developing the relationship with Zu and the other characters. The story is great.
