Source plot synopsis — includes the ending
In the distant future, Gary and his cat Kiki are piloting a spaceship to a distress call in an alien planet. While flying towards the planet, Kiki steps on the ship's keyboard causing the ship to crash land. Both survive, but Gary is trapped with the wrecked ship, while Kiki is outside of it. Gary then sends Kiki out to find a mech suit, explore the planet, and find a way to get off of it. Throughout the world Kiki can discover voice logs which speak of a mad scientist obsessed with keeping his sickly dog Barkley alive. Additionally, as Kiki clears out the planet's systems to gain access to the lab, they repeatedly encounter a talking rat, who is eventually revealed to be the mad scientist, transferred into a different body. He confesses to using a false security alert to lure Gary's ship to his planet, in order to steal Gary's body. He transfers his consciousness into Gary's body, and plans to save Barkley by transferring his consciousness into Kiki's body. The scientist successfully destroys Kiki's mech suit, but she uses the passcode (MEOW) to free Barkley from his hydroglobular tube. The scientist appeals to Barkley, but he attacks the scientist and incapacitates him before leading Kiki to a spaceship. They escape the planet, leaving the scientist behind. It's implied in the post-game that Gary escaped with them in the scientist's former rat body.
