Thanks! Unfortunately the X does mean you got it wrong. As a few folks have commented, the method for playing the game is counterintuitive, because we designed it to fit the theme. The goal is to remove words that are not part of the solution, leaving you only with the four correct words that form the puzzle solution. We think a future version should be the opposite, where you select the correct words and are only allowed a few misses. We really appreciate the positive reception from everyone, even if the gameplay for this version is a bit counterintuitive!
