edited response: in addition to the original confusion created by a prior version of the new account screen, it turns out there was a minor bug that caused the game to incorrectly tell you that your traits were wrong if you didn't enter a character name. It has been fixed.
I got all the way to level 13, but that level never ends. Once all the enemies go, I just sit there firing into blank space and the level never ends. Shame, because I actually thought the game was more exciting than I first thought.
OK I think it was because Kongregate was having problems earlier - I was getting "kongregate is currently unavailable". I've just tried it again, and it only took 15 seconds.
I will fix this for you. [: Cancel that, the file got deleted. :/
