Would both players then have to be on the same seed? If so, how would you ensure that? My guess is at the start the very first cryptex would generate the seed based on the combination of both players' set symbols, otherwise I don't see how it's possible to have any kind of synchronization in terms of the seed.
This is probably the first time I've seen this mechanic applied to any game and I think it's pretty cool. If there is a way to fix that bug though that would be great for any future players who could run into it cause it made us (me & my teammate) feel dumb and then when I decided to check my teammate's screen I realized that seed (I thought the whole level as I was unaware of seeds being a thing in this game) turned out to be mathematically impossible the entire time.
I don't mean to say that I don't like the game; I love the game. I just think it could discourage players if they get the short end of the stick here and I'd hate for such a cool game to do poorly simply because of one small bug.
