How are we supposed to utilize Electric Currant? It seems like zombies need to somehow pass through EC in order for it to deal horizontal damage, or zombies need to be blocked with Wall-nut for it to deal vertical damage. Are we supposed to use Garlic and Sweet Potato?? If so, it's very useless because I'm not gonna bring those plants ever.
