Cool concept; still too hard, I'm afraid.
As a concept, it's pretty cool. Who doesn't like a typing game where you press keys to blow up an alien spaceship? The only problem is, the new version is STILL too hard. I'm a pretty good typist, and even I found it too difficult. You should try adding less beats in the beginning so that people can sort of keep up. You should also make the keys on the bottom more visible, so that players can see what key they should press next. I didn't particularly care for the music -- even though it was fitting for the alien theme, I didn't like the bleepy-bloopy synthesized notes. But, that's probably just me. :D
However, I think that most people will agree with me with the fact that you still need to tone down the difficulty a little. Other notes would be that the warning, though it is present (a good thing), is a tad long. Shorten it, and make the game less hard, and I (and many others) will enjoy it more.
