Alchemist TD is a remix of popular Flash game Gem Tower Defence. At the start of each wave, Players are given a randomly-selected set of five gems with which to place onto the field, combine into stronger basic gems, or combine into various special gems. When a gem is placed onto the field, the remaining gems turn into rocks, which can be placed anywhere on the field. Some creeps have special abilities such as regeneration, swarming, and fast movement speed, so think carefully before placing any gems onto the field!
