Good, suggestions.
Very smooth. As noted in other reviews, enemies is misspelled. Also, either the font needs to be different or bigger, as I had trouble telling some letters apart on the balloon. The D's and O's especially. I've seen in other typing games a way of scoring each individual word. Like rank A B C D, etc. for typing speed and accuracy of each word. It does get a bit repetitive. Extra modes, being able to set the difficulty of the words, different enemies, and bosses would be nice touches. Also, after each level a general overview of your performance with perhaps the option to save. Bravo for making a game like this.
