Thanks! I've not tried to figure out the maths of the difficulty dynamic: more words is harder, but it also increases the chance of a letter guess being correct which seems to balance. In-family testing suggests that it's usually solvable. I agree on the plurals. There is a limit of 3 on the number of words that can end with any particular letter.
