The concept for your game is cool, but overall needs more polish. For example the gameplay comes off as fairly boring, since you are only typing, and have no other stimulus since there is only one background image and no music. Adding something to keep the player's attention would definitely improve the game. Another thing that would benefit the gameplay would be to have some better feedback on getting something wrong. The text turning red doesn't indicate much and this was a problem when I didn't type a space and thought it was the first letter of the word I was messing up on. It would also be nice to see menus that are more fleshed out rather than a menu that's just a default start button with no background.
Keep up the good work though, with some more time spent on it this game would be pretty interesting.
