It's less a game than an interactive mental illness simulator - with a pretty neat art style.
Neverending Nightmares is "designed to explore the darkest and most negative emotions — fear, horror, anxiety, hopelessness, pain, and frustration. It isn’t a typical game where you are faced with challenges and can win. We worked really hard to make players feel trapped and helpless when playing the game. After one reaches all three endings, none feel like a happy resolution. They barely feel like a resolution at all because there really aren’t clean endings in life."
The PC release has a 68 on Metacritic, but it was also called "emotionally resonant" by Game Informer so... Worth noting.
