Towers Defending: Attack of the Enemies

How to play

The board at the bottom of the screen acts like a 2048 board. Swipe the towers across to upgrade then to higher tiers. To place a tower, click and drag it onto a tower spot on the top half of the screen. Towers can be sold once placed, so you can replace them with higher level ones later on. Picking up a tower on an elemental tile turns it into a special tower of that element. These special towers have different, powerful attacks, so be sure to use them wisely.
