>>7173393121 is a PSP game, and has the scale and depth of one
there's no mechanical progression or expansion
you get light and heavy mode which feel cool but dont really help
Kat herself never progresses
the world is bigger and better, the music is great, but theres no game
no exploration of gravity mechanics, just mash kick, and homing gravity dive into the giant vulnerable point, or activate special which does that for you
