Clockmaker is designed to be a difficult game. Players will often need more than one attempt to find the right strategy and complete a level. Please note that having boosters, tricks, or helpers gives you no guarantee of winning. Bonuses are designed to help you play, but you still need to use your moves wisely and employ these items only in cases when you are confident that you are close to winning.
If you think that a level is genuinely impossible to complete or that there is some problem in the level that prevents you from completing it, you can always contact our support team and share your feedback with them. Don't forget to attach a screenshot of the level (and the problems in it), so that it is easier for the support team to find the level in question and deal with the situation.
