The Whirling Tower is a 3D Tower Defense game in which you play as a defender of the Bacab temple (which looks a lot like the Kukulkan temple) against hordes of conquistadors.
You upgrade the different sides and levels of the tower separately and can rotate them so that the different faces may side different fronts of invaders. The game is from a new Belgian designer and publisher.
You can finally have a look at the components. Behold the mighty Tower!
