Thank you!What through you off with the first puzzle, Did you expect it to have no diagonals?
The introduction puzzle puts you in mind of a phone screen, in fact I mentally read it as connect 4 to 3 to 2 to 1 even though the game did not show that.
Having it not be straight would be just enough I think to change the mindset of a player.
I see, thank you for the effort!
