I agree Sparteye, the exclamation mark makes "Wordapazlooza!" look bad. The way the Goodnerds designed the standard font on computer faces is not conducive to good visualization of an exclamation mark.
Besides, an exclamation mark serves as a symbol to denote emotion, and not as a hysterical symbol to announce a sentence end. And further, the average eye does a double take to make sure that the "!" is not an "l".
Let's be honest, the word "Wordapazlooza" isn't that pretty anyway. I tried putting a space between "Wordapazlooza" and the exclamation mark, but that looks pretty stupid too.

Glad I could help,
Milum!
