GamesRadar: "If you’re sick of the same old formulas and you’re open to some indie eccentricity, Retro/Grade is just the trippy time-sink you’ve been looking for – and it’ll finally give your dusty plastic guitars a use past Rock Band and Guitar Hero. Fans of bass-heavy beats and slick space-age visuals will find a lot to love in this psychedelic rhythm gem – just make sure you don’t jump directly into the highest difficulty, lest you frustrate yourself beyond belief." 3.5/5
