Would agree with all the other comments - the pre-rendered backgrounds and the character models are both absolutely fantastic, managing to be both very 90s and also very original with the strong colour palette and very distinctive camera angles. The standout model for me was the teacher from the maths class, the red colour really stands out and the swaying was kind of unsettling to me.
World building is great. Dialogue is nicely open, with clear themes but plenty of room for player interpretation.
