The document outlines a design for a side-scrolling adventure platformer video game called "Squidiverse". The player controls a squid who must travel across various planets to rescue his father, who has been kidnapped by King Crab. Each planet has its own unique visual style and gravitational properties. The game will have an 8-bit retro visual design and feature sea creature-inspired characters. The squid character can jump, throw rocks to attack enemies and solve puzzles across multiple challenging levels.
