Fun? There needs to be better indication of how and where to get letters when they are necessary to proceed. I had all but 3 or 4 letters, but couldn't figure out where to go next and I'm pretty sure I was completely trapped. Also, the starting letter shouldn't be dependent on the entered name.
Definitely fun, but the skill of the AI players is incredibly irritating. I frequently see them chip straight into the cup from long distances like they were playing basketball.
