This game is addictive and challenging and even has a companion watch app! The one thing that is so, so, SO frustrating is that the "go" interaction during the game is the same as the "start over from the beginning" interaction after you lose, with no way to undo it. You have the option of continuing within a few levels of where you left off, or you can start over. Tapping the latter means you potentially lose hours of progress because of one stupid move that doesn't have to be designed that way. Really, really frustrating. Would love it if "start from level X" was the main call-to-action vs. "Hit this button to lose all your work and cry."
