Alchemist Tower Defense

You must use a special combination of strategic planning and fast decision-making abilities to protect your base from a barrage of monsters in Alchemist Tower Defense. You are given five jewels per round, one of which you can keep and the others of which you can turn into rocks. Then, using these rocks, you create an intricate labyrinth that will halt the monster's progress. You can use the cash you receive from each successful defense to create unique gems with enhanced powers like poison or stun, as well as to buy better gems.
