This is a really cool puzzle! As others have said, definitely need better instructions for how to actually make moves, I spent a good amount of moves figuring it out. Also, it would be a nice addition if there was a function to share your results, similar to wordle and other similar online puzzles.

A more out-there suggestion would be a replay (either on the puzzle itself or as a gif) of all the moves you made. Could make it more interesting to share with friends.
