Use your towers to take out the creeps. Build towers along the maze to destroy the waves of creeps. The sequel to Flash Element TD. Control the number of monsters in the maze at any one time by building towers which can stop them. Flash Circle TD is one of the miniature tower defense games, that is designed for quantity in a small optic. I enjoy this principle very well because I'd rather play with many towers. It is also a bit older and certainly known to many but it's always fun.
