Under the Alien Sky is a very short (~3-5 minutes) kinetic visual/sound novel created by Nicholas A. Ferrell just over 24 hours from July 17-18.
The view-point character is dreaming of an alien sky. She knows what she is seeing is not real, but she feels as if she had seen it before. As soon as she thinks (or dreams) about nostalgia, she has a eureka moment. She believes she had dreamed about this scene before. Her reasons are tied to two visual novels she had stumbled upon and read many years ago when she was a schoolgirl.
(Note: The two novels referenced in the piece were localized as part of al|together 2006.)
