Discover the depths of your soul with AETHERNAUT, an open world first person puzzle game in the vein of Portal and Talos Principle. Set in a claustrophobic steampunk world, you must solve puzzle rooms using light, sensors, portals and time travel to gather the aether vials and access the core of the Construct.

You are guided by the voice of Cornell, a disgruntled employee hired to probe you and better understand why you are able to survive the deadly aether. As you traverse the abandoned Construct, an unseen entity tries to make contact, pleading for your help.
