Thanks! It worked.
But what does this even mean?

They tell me 2 rules, tell me my password matches 2 of 3 rules, then tells me 4 rules must be met.
I found some other weirdness with Home, Page Up, and Page Down inserting characters (the letter "k") instead of navigating the caret in the text fields.
These minor quirks aside, this looks to be a fun game!
