That's awesome. I'm glad you got the joke of the dragon copying it down (fictionally yeah that's what happened, functionally learning how to make a minimap is on my to-do list for the next jam :D). That's super weird that you were able to get that key, it's the reason I specifically disabled movement during the tumblers section. But oh well, so it goes. I like the tumblers too. I've mentioned it before but I think if I use it in the future I won't bunch them all up together like that, but rather have them open up different parts of the dungeon instead (sort of like the wheel in Majula Shrine if you're familiar with Dark Souls 2).
Anyway, thanks for playing!
