In this fun Tower Defense game you have to stop the scary monsters from reaching the entrance portal to our world! You can place several defense towers in different places: the quick 'steam tower', that eliminates the monsters from a big distance, the slow 'eye tower', that's the most suitable to stop the monsters, and the super fast 'tower of fire', that fires flames at the monsters. There are ten cool levels, so they'll keep you busy for a while!
Click there, where you want to place a defense tower and then choose your tower. Use your mouse for all the other actions, too.
