If it is the first password, make sure that the capitalization is correct. Try it in all caps. :)
Right, I was typing it in all caps, but the problem is that it's just not letting me press enter at all. But I think I know what's going on, I was running the game from the itch.io app and that probably screwed up unity's file permissions. Going to try running the .app directly to see if that fixes it.
