"Retro/Grade, to put it simply, features the most fresh and creative central mechanic we’ve seen in gaming since Portal. Retrograde, the word, is defined as inverted or reverse motion, which is the basis of Retro/Grade, the game; essentially a sidescrolling shooter which is played in reverse.
Now, reversed gameplay means that you won’t be firing energy blasts, but instead unfiring them to collect them back, as if you were hitting notes in a rhythm game such as Rock Band. It’s all synced up with the brilliant electronic music, too, making for a unique take on a tired, dying genre." 9/10
