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 scientist helpîng you through the experiments and seeking to better understand who you are as a person by asking challenging philosophical questions:

Would you rather be remembered forever as an evil tyrant, or be completely forgotten?
Is happiness or usefullness a more important purpose in life?
When we fall in love, do we love the real person or just our idea of that person?

Your answers will guide the path of the story as you learn why you are able to survive the deadly aether. But as you delve deeper into the abandoned Construct, an unseen entity tries to make contact, pleading for your help.
