I've actually asked friends to playtest while I was watching instead of recording playtests just because I wanted to see the frustration happen in real time. It's very fun to watch. Usually when I do a team project, I get shoved to UI because no one else wants to do it (which is understandable). So for this project, I thought it was time to let out my own frustrations with UI by making it breakable and bad. Unfortunately it was more difficult than making good UI.
Thanks for your comment!
