How to solve a problem that does not happen to all people?

RUPAS

Hello, one of my games are getting some negative reviews because they have problems with some puzzles, is very strange because my the problem never happens, I try reproduce the problem on different devices and the problem never occurs to me, also I have clients who say who have not had problems with my game, however I have other clients who say that if you have problems, I'm going crazy because the code is simple and works very well for me, but there are people who do not work ... GameSalad is a problem?

Are we talking about iOS or android and what exactly is the problem? Without more information we can't help you. It's like going to the doctor and saying It hurts but not telling him where it hurts.
