Ether One

Ether One is a first person adventure that deals with the fragility of the human mind. There are two paths in the world you can choose from. At its core is a story exploration path free from puzzles where you can unfold the story at your own pace. There is also a deeper, more adventurous path in which you can complete complex puzzles to restore life changing events of the patient's history in order to help the validation of their life.
