I made a joke about being sponsored by keyboard manufacturers in another comment, so I'm not gonna repeat it.
The game is really hard for me because it takes some time for me to react to appearing typos, and the timer seems to be pretty tight (btw, I corrected all the typos :D). Although, I liked how it discouraged repeatedly pressing one key by making a ton of typos, that's definitely what was needed to force players into pressing different keys, nice touch. Also, I wish there was some kind of game-over screen instead of just hanging.
There's not much to say about graphics other than it's simple and does not distract you.
To sum it up, you did a good job on this one!
