> How to improve the game, so that more people finish it?

I tried to play today's and failed after 5 attempts. The attempt feedback is borderline incomprehensible to me, even with the tutorial. I understand what it's telling me, but it doesn't actually help me.

I ended up with red lines all over the place, and they moved around whenever I made another guess. I had a solid green letter that was wrong, because it was a subset of the real letter.

I'm not sure if I'm meant to break out graph theory to try and incorporate the feedback, or just blindly stab in the dark. Neither really appeals to me in a daily puzzle game.
