I want to say that, that’s exactly what I like. If people give me bad feedback, I can improve something. If I only hear “yeh, looks good” from friends, I would never know what people would really think about the issue.
Listen to bad feedback, and improve. This works not just for games or websites, but life and work in general. Ask for the feedback, ask what’s bad. Be specific. Listen to what’s being said and think of how to improve.
