When you press "Start" (n) you will see a "wave" of insects entering the arena and moving from top to bottom and from left to right towards the "exits" of the arena. Each time a bug reaches the opposite side of the arena, you will loose one "life point". The amount of life points is shown in the center of the menu-flower. Construct barriers to prevent the bugs from finding the exit. Place the forces of nature (synonym: building blocks or towers) from the menu-flower where ever you want inside of the arena. Depending on your wealth (coins) you have to choose which "elemental" tower fits best according to the "elemental" bugs. Towers can be upgraded! It's often better to upgrade towers than to buy new ones. Every elemental force has its own damage value and range. By clicking on these you can display their detailed information. HINTS * Forces can be upgraded! It's often better to upgrade forces than to buy new ones. * Force the bugs to walk the longest possible distances. * Try to "juggle" with the bugs: close and open your labyrinth at specific spots to keep the insects trapped in your construction. You are allowed to switch openings in your construction by removing or adding towers and redirect the bugs on their way towards the exit. Remember that you cannot fully close the exits!
