I liked the backgrounds and the simple design of the characters.
However the story just doesn't make sense. (Spoiler alert!!!) You are a smart student who has a bright future but are often bullied by your classmates and "used" by your physical education teacher. Until you meet a girl who teaches you not to let people walk over you. (this makes sense t'ill now). But by the end of the story you turn into a complete ass.
So to make things short you turn from smart intelligent kid to a jerk.
