I gave this a try, and I swear I reached the word limit and it didn't release me! I started just typing gibberish to see what would happen.... and nothing did.
... I probably typed an extra zero, and put one thousand instead of one hundred.
But long story short, there really is no way out. I even tried CTRL + ALT + Delete. It's a pretty solid lockdown, haha. I had to restart my computer. O_O
