However, when I guessed "MEATY," the A was marked yellow for the left word. That being the sixth separate letter marked yellow (A, E, O, R, T, and V) for a 5 letter word, the word was unsolvable.
Oh yeah, somehow I didn't notice that. Well it obviously doesn't have 6 different letters in it, so I guess it's a glitch!
EDIT: And I didn't notice the var text color, which I guess is the reason 6+ letters came up positive. I bet it will be easy for the developer to spot the problem from that hint.
