Woah, its impressive how polished the game is! Nothing feels unfinished or out of place, and the puzzle minigames are creative, fun, and all work well! It is admittedly really difficult, but that makes me want to play over and over!
I'm hard-pressed to find a point of critique, but maybe a screen where you can see the puzzle types you've encountered thus far and how to solve them? From what I've seen though, they are all simple enough to understand after a minute of rotating the vault.
Honestly really great submission over all!
