Flooper88, restart and update 2x speed, 1x strength and so on and your units will be that fast that they won't be shot to bits before they can reach the enemies next nest.
Sir "Click alot" just invented another game. Has lots of bugs in it as p.e. "you may play this won level over and over again" instead of progressing to the next one.
This game simply s*cks, I don't understand how it can have a rating of "4269 ratings (3.68 avg)" atm.
