Title screen of Demencia
Demencia is a Yume Nikki fangame made by mva-g45. It's notorious for having literally hundreds of music files stolen from other fangames. It has since been claimed to have been finished and will no longer update.
The creator doesn't want anybody to talk about this game or play it again.
You play as a girl named Miko, who dreams by interacting with a quilt. Miko can leave her home and access the ending right from the start due to a bug.
