Got to 7406 @ 86%. Fun game, but a couple of annoyances:
* Font made some letters hard to distinguish
* Enemies can be targeted when they're not even on the screen yet
* Those two combined create a frustrating gameplay situation. I'd hit a letter, then realize I had hit the wrong one, and my ship would be locked onto a word that was off the screen. Until that word came onto the screen, I'd be a big fat sitting duck for the OVER 9000 other ships. Cue mashing buttons and plunging accuracy score.
Powerups would be fun. Like a multi-shot where you could push one key and fire at multiple enemies at the same time.
I still think the best typing game ever is Typing of the Dead.
