You are a participant in Project Threshold, an experiment designed to force people to confront their deepest fears. Pass through sets of blue and red doors, survive what waits beyond them, and reach the end, if escape is even possible.

Project Threshold is a psychological horror and memory-based walking simulator where players must confront the fears and horrors waiting beyond each threshold.

ESTIMATED PLAYTIME: 30 - 60 MINUTES (Varies depending on the player's choices and performance)

⚠️ BEFORE YOU PLAY

Project Threshold does NOT feature checkpoints and is intentionally designed around memory-based progression. If you are caught or die, you will restart from the beginning.

The game consists of 10 sets of doors, where remembering previous encounters, recognizing patterns, and learning from each attempt are core parts of the experience. Every run is meant to build your knowledge, making each subsequent attempt easier.
