I would add that the answer detection logic should probably get beefed up a bit as well. When I solved today's puzzle, it counted "race car" as a wrong answer when it expected "racecar". It should accept both forms of a compound word (also "racecar" isn't a word but that's more minor).
There's an ambiguity here between palindromic words and palindromic sentences (where punctuation and spacing are non-breaking):
"Go hang a salami, I'm a lasagna hog"
or
"A man, a plan, a canal, Panama"
though it seems that all of the answers (in the one tutorial and one round that I played) are single words, often slid in as character insertions. Just go light on the spacebar, apparently.
It wouldn't be accepted by a palindrome-detecting function but it would generally be accepted by puzzle-solving conventions (e.g. for crosswords), which normally ignore spaces.
