Game is buggy, as others have mentioned. Either that or the scoring makes no sense. Why did it say I had 4 vowels correct, if my guess contained 4 vowels and one of them wasn't in the final word?
If the target word contains two E and my guess only contains one E it should say 1 vowel correct, not 2. Isn't that obvious? What am I missing? I presume you made it this way for a reason.
Word: METER
Guess: KEXXX (two vowels correct)
Guess: KEXER (two vowels correct)
