Okay better review this time. Don't pay for no ads it doesn't help. Don't spend your currency on the heroes either. No matter how much armor they have they go down in 1 shot just like your little dudes. There is NoSKILL involved in this. You cannot save your troops, just got to accept that some will die. Weapon upgrades do nothing, income upgrade does nothing. You could not touch the screen and will win 60% of the time. Avoid this game
