Missing a lot if real words; i.e., pierce, deet, teed. Should allow swear words that are in the dictionary.if there they should count.
See above. Missing real dictionary words. Should allow British, Canadian & American spelling.

Two letter words aren't allowed
Agree there are too many real words not counted and yet adding Ed I got and Er is!
SO many legitimate words missing. Seems to be only Americanisms and American spellings accepted. Needs a much more comprehensive dictionary, as I’m starting to find it very repetitive after 900 levels! Plus there have been several letter sets which have appeared more than once - that’s cheating and lazy!

Can’t believe how many words are missing from your list! It’s as though someone who doesn’t speak English designed this.
