Upon entering the game, what struck my eyes was a rather rudimentary style of graphics.
How should I describe it?
4399?
The visuals were undoubtedly 2D, and from a top-down perspective.
All the buildings lacked roofs, displaying the interior structure directly; simple lines delineated walls, classrooms, and playgrounds. Even items such as desks and podiums were essentially composed of three or four basic lines.
As for the characters within, they even more fully embraced a simplistic doodle style, predominantly featuring exaggerated chibi representations with only a handful of basic actions.
It was blatantly obvious that the students and teachers all followed fixed templates, with hair, facial shapes, and body types combined at random - crude beyond belief.
To exaggerate a bit, the style was so basic that many enthusiasts could recreate it with their computer's built-in drawing tool.
