In Astrolabe, you are an astronaut who was knocked out of orbit of a planet and crash landed along with a shape-shifting alien. You must work with your new companion to gather magic relics and ship parts, enabling you to travel from one planet to the other, and eventually return home. As you gather magic relics, your alien companion will gain more abilities, such as gliding and double jumping. The goal of the game is to collect the magic relic and ship part one each of three planets, after which you will win and be sent home.
