damn this game is glitchy, i completed a lvl and it didnt go to the score screen, also some of my rockets keep going off screen when an enemy gets past and does so over and over!
this game is so easy!! just get electric towers and guard towers or wtever (the crapy 1s) then just upgrade them and buy up good towers... simple, then when u get 2 a lvl u cant win go back to and easyer lvl and get a ton of upgrade pts, easy... upgrade money 1st then str then reload time
