What the sources establish
The escape loop documented by the official game description is simple to state: retrieve four keys and one code, then work toward the exit. Keep a mental record of opened routes and return points as you explore; this makes a failed search less costly than treating every corridor as new.
Use the evidence carefully
The materials do not provide a version-stable, text-verified order for the keys or a universal code. Use the linked full walkthrough as a visual companion and verify the interaction prompts in your current session.
