This isnt an offence game... its a stragetic defence. YOu shouldnt need more than a few good protectors. its not like you can attack the towers or anything, thats what spells are for.
i agree with thunder, i always want to check if it was a perfect tunnel, but when i do i miss a gate or crash. Also, the scoreboards shouldnt reset every 2 hours :/
There are two warnings checks before you actually hard reset your game, you should be safe enough even if you press it accidentally twice :)
