About this game

PARASYM is a raw and visceral interactive fiction. You play as a rat in the streets and sewers of Paris, and every decision shapes your fate.

STAIRCASE E
Friday, June 12th, Building C closes for good. Five of you enter through the service entrance and don't leave until dawn. What you were looking for was one last night in a student association's office. What you find is what the university packed away in a box in 1999.

Thirteen endings. Nine hours of reading.

Here, your choices matter. Some open doors, others come at a high price. At crucial moments, a roll of the dice puts your survival on the line. Your stats (food, health, stress, status) change throughout the story and influence what happens to you.

The narrative branches out towards 8 different endings. On the last page, a screen reveals your ending number and name, the percentage of your playthroughs that end there, and the percentage of players worldwide who achieved the same ending. Where do you stand?

- A handwritten, dense, and immersive story
- 8 unlockable endings
- An illustration panel accompanying each chapter on tablets
- Subtle soundscapes
- Fully bilingual (French/English)
- Free, with no intrusive ads or addictive mechanics

Parasym = parasite + labyrinth.
An interactive fiction where every choice leaves a trace.
