I like the concept but...the words I went out on were ABYRENE, AURILLIAN, and IMPASIVE, which as far as I can tell are, you know, not words. I guess they could be words in a way that CKOFUTAU can't be, but still, it's a little weird to be playing "identify the fake word" and lose because you identified fake words.
EDIT: when I restarted, I was given WORRY, USURP, ESTOP. Which is unfortunate because all three of them are words...
