This is a very innovative defense-shooter.
Each attacking robot has a colored symbol on top of it,select the correct color and draw the corresponding symbol (anywhere on the screen) to shoot an arrow to this robot!
As the game progresses you'll earn spells. To invoke a spell you will use a unique symbol that you previously created!
As the game progresses you'll have to start mixing the palette colors, in order to get the right color to kill the robots!
