Not many tower defense games out there that are usually worth my time, for the exception of yours of course. Great units both the players and enemy, great music and awesome game play, Love the noticeable change of difficulty totally loved it. No hardcore player or real player would ever complain about difficulty 'cause real players love putting there skills and wits to the test and your game did that beautifully.Only thing I hated about your game was that it's not long enough, cant wait for the next one great job keep it up and stay true for the real gamers and keep that challenge on.
