Explore the mysteries of memory in Paramnesia, an interactive detective visual novel. Follow protagonist Maria as she struggles to understand herself and navigate the conflicting opinions of two radical sects. It's up to you to delve into the depths of her mind and uncover the truth. But beware – some of her memories may be false, and it's up to you to distinguish between reality and illusion.

In this non-chronological tale, you'll use a file grid program to access and navigate through Maria's memories, searching for clues to help you solve the mystery. You'll encounter six different types of files along the way: Confession, Etude, Database, SMS, Additional files, and Encrypted files. You'll need to choose wisely in order to unlock the full story, and ultimately, discover the truth. With three possible endings, only one will reveal the full truth of Maria's journey.
