Increasing app reviews involves delivering a great user experience, politely asking for reviews at the right moments, and actively responding to existing reviews. Ensuring your game is enjoyable, and bug-free encourages users to leave positive feedback. Ask for reviews in a non-intrusive way, ideally after players have experienced something positive in your game. Engaging with the reviews you already have, whether they are positive or negative, shows players that you value their feedback and encourage others to share their thoughts.
