This is pretty cool!

Would like to see explanations for the connections which are sometimes not obvious.

Maybe make a video showing how it adapts as you make guesses. I wasn't sure what was happening when the first green arrow showed up.

I also like NYT Connections and have the feeling a better version could be created that would, like this, let you try out 2 and 3-word groupings visually before committing to a possible red-herring.
