I played White Board Tower Defense. The first thing that came into my head after the 5 minutes was "Difficult" Many people would think this and simply write bad. After a little bit of thinking I came up with this. "I didn't really like this game because I found it too difficult. Even in the early levels. I guess I don't have the mind for Tower Defense."
