The environments are gorgeous and feature details such as volume meters built-in various places, making the world come alive with the music as you go zooming by (in reverse). The Standard ship is amusing - it's a stylized old-school rocket with a convertible cockpit, where your avatar, Rick Rocket, is sitting there with his space suit on, his helmeted head be-bopping along to the beat. However, as you play through the Challanges Mode, you can unlock additional ships, including a Minecraft Ship and a T-Rex in a crude rocket fashioned out of a tree. It is to laugh.
Typically, one of the most important things about rhythm games is the music - specifically are the songs popular songs and are they performed by the original artists. Retro/Grade isn't that type of rhythm game. The music in Retro/Grade is original Electronic music with an old-school 8-bit feel, but with higher sound quality. And, while you don't already know the songs, they feel "familiar" if you played games back in the day and they fit the visuals of the game perfectly.
When you unlock music via the Challenges Mode, you can do more than just listen to them. The music player isn't just a music player, but is, instead, a DJ console. You can load music from the game into both the left and right side of the deck, then alter the play speed of the tracks individually, cross-fade between the two sides and even "scratch." This game achieves greatness by stuffing every nook and cranny with pure awesomeness.
