Kretures is an obstacle laden, open field, Tower Defense game for the iPhone and iPod Touch with:

1. ★ Very large maps
   

2. ★ Calculating creeps that avoid your defenses
   

3. ★ Teleport towers to let you expand to the far reaches of a map
   

4. ★ Enemies that attack by land and sea
   

5. ★ Levels with multiple Creep spawning Grounds
   

6. ★ A Unique anti-ping-pong mechanic (tower destruction is 'free' ... but destroy too many, too quickly, and it will cost you!)
   

7. ★ carefully balanced, endless waves that will challenge even the most experienced TD players ... before eventually, inevitably, overwhelming them
