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.
