You act as a Crystal Defender, with help of various Heroes.

While monsters flood toward the Crystal, you must:
* Dynamically adjust heroes facing direction!
* Dynamically adjust heroes positions!
* Dynamically use magic card to attack monsters or strengthen heroes or even change path!
* Wisely choose items when Crystal Level Up or Boss Coming events occur!

You will find yourself very busy in the game, which is quite different with other Tower Defense Game currently, because this is an Action Tower Defense Game.

Of course there are a lot of ways to strengthen heores power like other rogue-lite games, and it's easy to become stronger.

Hope you enjoy the game!
