Typer Shark (hello, RSI). 2568806 points, level 23, time 57:03 (yes, it sucks you right in - and I was bored), words per minute 76, accuracy 97% (goddamned white piranhas, purple and green sharks messing with my accuracy), rank Ultimate Nautilator. I got to level 20 with 9 lives to spare, then level 22 and 23 ate them all up. The hell am I supposed to do when four red sharks are flying at me so fast I can't even read them? Grrrr.
(By the way: all difficulties, even expert, are very much doable, with the exception of "x-treme!". Within the first five seconds, at least 30 piranhas, a good 75% of which was white, and two were red, were flying at me. Not fun. But if you like dying in the first five seconds, or really getting RSI, be my guest. :p)
