Yup, that worked. But like XxxDemon_hunterXxx, I don't think I would have gotten that ever without the hint. The door code being six digits long makes it look like the answer could potentially be six digits, which obscures the solution. Even if the door code were only three digits (i.e. without the extraneous leading zeroes), I'm not sure it would have been obvious. It didn't occur to me to try counting the statues in groups of hundreds-tens-ones. I wasn't even sure if those were the statues I should be working with since I couldn't even interact with them, meanwhile there were a few "lifelike" statues I could interact with that seemed like they might be important (the only clue they might not matter here was the broken bust tablet).
I'm not sure what you can do to make it more obvious, but I'll be curious how many people get it before they read the hint.
