Then Desktop Tower Defense is the game for you. Get your quick fix of tower defense goodness with this awesome flash game. My personal best is 5203. I was only able to get this by designing the maze on grid paper before hand. After that game, I realised you can click on “send next level” and get bonus points instead of just waiting for the next wave of creeps. The game is highly addictive so to say that it’s a “quick fix” may be somewhat misleading.
