About Ultrafun
Ultrafun is about caring for the last fragment of Planet Ky, a world destroyed long ago by the Greater Void within it. The Kyzt formed into a single Kyztling, Qubert, in a last effort to tether itself to our world. You are a renowned scientist helping Qubert restore Planet Ky’s ecological balance and reconnect your species with the Intergalactic Federation.
Care for the Kyztlings
You feed your scientists ethically sourced Voidling cuisine and channel your progress into a psychic relay, a natural, vaguely tree-like organism growing within the Ky Fragment. You can also make friends with the Kyztlings; this is a single-player game, and those friendships are virtual.
