VVVVVV's premise is simple. Your spaceship has crashed in a strange dimension, and you need to go find your 6 crew members. The controls are easy: arrow keys to move, V or Space Bar to flip your gravity. There's no jumping. You instead flip whether gravity holds you to the ground or the ceiling. You start exploring this giant, gravity changing world looking for your friends. At first, the level design seems random. Each stage is named (often cleverly and enigmatically so) and changes with each screen. Certain stages have their own rules (rooms that loop back into themselves, for example) so it's always fresh. The feeling of discovery and adventure runs deep.
