No, clicking on anything doesn't work. Clicking anywhere on the screen doesn't tip the dominoes and none of the buttons work anymore. This is with 1.2.1. Resetting the game seems to solve it but now I've gone and wasted my time and discarded my game for your game-breaking bug, so I won't be looking at the new content, let alone playing further, anymore. Maybe at least try and replicate the bug yourself before you tell people to throw their progress away next time.
