It's kind of cool, but it does have a uniqueness problem: when the game was expecting MATCH, it didn't accept BATCH (which was also formable).
Thank you for the feedback!
The current idea is for there to only be 1 possible solution word per round even though, as you said, there might be other possible words to be made in a round (just through the randomness of the letters). That being said, I'll definitely consider making a future update for multiple solution words in a round.
