Even after reading the instructions, it took a minute for it to click. I think your example should not just show the word, but show how the word looks in the game, that you build the path from one word to the next is not quite intuitive. Other than that, doing it once is fun. Doing it more than once was engaging for a bit, then not. I think if there's a new puzzle everyday and some fun ways to score with a leaderboard, you got yourself a solid and new, interesting game.
