Big fan of typing games and this executed very well. Beat on easy and lost on the later extreme rounds so kudos on the balancing.
I was curious about the content of the text passages but the end dialogue brought it all together effectively. Seriously (pun intended) impressive work to make a game this polished that also delivers delivers an important message.
My one suggestion is to have the "lose" ending somehow communicate the same idea or hint that you won't get the full picture until beating it. If I had only played once and lost I wouldn't have gotten the full impact of the game!
