cavalry is best --- T I P ---: you wanna have enough points for the final levels? play 20x the easy CRADON CRAG on level VI ("Ephira") only with upgraded cavalry. you get so many gold to upgrade your whole army. good luck boyz!
Actually the weapons are very balanced and effective in different situations. The Electricity is great for a large group of Fruitflies. The Laser is most effective against Mosquitos because they stay in a line (and you can switch to it while your Electricity recharges). The Flamethrower can annihilate bugs caught in your webs, and the Rockets can deal heavy damage to the larger bugs in the wave because you can select your target. Fire one off and switch back to your other weapons to maximize damage.
dont see enemy at the beginning - why? zoom would be good. cannot boarding...bug = the enemy "fidgets" only on screen. idea and graphics are very nice.
from starting level 4 difficult. too many experimenting to get best combi of towers. these should be to click and drop, not to push across the window. idea and graphics are finally great. (whats best combi-tower?)
