Really fun game. I love these typing games and I think you put a good twist on it, incorporating the theme in an interesting way.
One issue I had, was that I have a german Keyboard, so "Y" and "Z" are swapped. That means that some letters player 2 must press, are the keyboard side of player 1 and the other way around. I don't really know how to fix that and it probably doesn't matter for the majority of players, but it would be nice.
But regardless, this is a great idea that got executed really well. Good job!
