Damn this thing just refused to give up. I felt like I kept getting numbers, but none of them ever opened up the puzzle.
Eventually I tried to exclude a combination and just ended up running through so I can't really say I "solved" it.

Really nice. Close to three stars for me because of how long it took + how difficult it was for me to see the final bit that broke the puzzle open. Thanks for sharing.
