Better to maxed out the scratch level 10 ten firzt and finizh the game. Later ztart a new game again and kill lezz than 40 (dont get the scratch powerup).
the lazt level iz eazy,juzt conquer another hive up to 10 and ztart to produce a new bug... zince u will produce armored unitz,take it the long ranged bozz firzt zince they will retreat if the enemy got clozer... if 2 bozz remainz,gather up to 25 unit to attack the armored bug and u can now eazily defeat the flying piercing bozz...
OK,that confuzing.... the control are zux...
