Cool game! I died the first time due to those darn metal detectors...or I guess not-metal detectors? giving me away, but I was sneakier the second time. I picked up the fifth clue and got back to the door, which had been blocked. I'm not sure if that was the end and you're just doomed, or there was another way out? The sound design was well done, I enjoyed the suffocating silence of your footsteps at the start, it really makes it impactful when you start hearing those mechanized movements.
