I actually found this really enjoyable!! Maybe I'm too silly, but there were a few letter combinations that seemed impossible (think "vma") and I couldn't find a way to preface the letters given. Otherwise, I'm a speed machine.
Thank you! You're actually very serious - I have gone through and checked if all of the starting letters (trigrams) actually have valid words in the words list - vma had none! As did 11 other pesky v starters. So that shouldn't be an issue from now on! Glad you enjoyed it!
