User feedback for your game is one of the most important things you can do to determine if your game is fun or not. Note that user testing is not the same as running a focus group on your game to squeeze out the last ounce of your indie personality. No! Think of user testing as similar to when comedians try out their new routines on fresh audiences at tiny clubs. They do this to hear which jokes hit and which jokes bomb before they perform them at bigger venues.
