first solution word i got was "DONNA" which was kind of rough to guess. second game it told me "DRAPE" wasn't a word. the game worked fine though, thanks.
there's an everyday variant also at fiveletters.xyz
It seems the list I downloaded is very much incomplete. I should change the message from "Not a word" to "Word is not in the list", it would be more accurate.
But DRAPE is a word: https://dictionary.cambridge.org/dictionary/english/drape
I downloaded the list from an online dictionary, I would be surprised if it weren't.
