I decided for the Tungsten font over Helvetica/Arial because I felt it fits the game esthetically. I know that's a, from a user experience perspective, pretty stupid reason, but making this game look good was one of my priorities. Maybe I can shift a few pixel on the t/f to make it more clear.

I thought long about how to implement a highscore list, but with a JavaScript game there's really nothing stopping you from submitting fake scores. Even if I verify each word on the server side, a bot that plays the game would be trivial to implement. I have no idea how to make it at least a tiny bit "secure" :/
