I always really adore the most creative games at game jams, and I believe that you've just made one. The typing mini-game is such a cool and out of the box idea that it makes the game very addicting, maybe even just to see what the next word would be :D.
One thing that I'd say is that it was quite weird to let go of the mouse every reload to type the text. Maybe all the player interaction should be contained within the keyboard?
