Geometry Defense: Infinite

Action Tower Defense
Geometry Defense: Infinite is mainly modeled after the WC3 tower defense mods and why mazing is a core part of the game. Some differences you will notice is that enemies cannot destroy towers and the speed of the game.

The design goal of GD is sort of "anti-TD" in that playing idly will be punished. My goal with each mechanic is to force player action and higher actions per minute (APM). Enemies are designed to annoy you and disable your towers in other ways. I understand this is not for everyone but there are many really great tower defense games out there if you want something more traditional.
