The official developer categorization for Astronoka is "Space Vegetable Production & Pest Control Game," and that description is a fairly accurate one. You are a farmer of a future distant star system, dreaming of being the greatest farmer in the universe by winning the All-Universe Vegetable Competition. However, you must first concentrate on conducting some Mendelian tinkering with the Hybridization Machine and successfully producing better seeds.

Another other job is to deal with the 14 (and evolving) species of a pest called Babu, whose purpose for existing is to overrun the your entire crop. You must continuously update traps and defenses to protect the field against these ever-cunning pests. Once vegetables reach harvestable point, enter them in one of several dozen vegetable contests that take place.

Every victory gives the player-farmer greater celebrity status, and people in the star system begin to react more favorably to you, allowing access to new locations as fan letters and words of encouragement trickle in. The ultimate objective is to win the All-Universe Vegetable Competition, with an "emotional ending" promised for pulling off the deed with the seed. ~ A.S. Kaku, All Game Guide
