An excellent castle to play as attacker or defender. As attacker, I recommend that you use the easy setting first. As defender, I recommend the setting at very hard.
With the rumor of an attack, LordGPain takes extra steps in ensuring the safety of his land. His newfangled fortification is nearly impenetrable and army even greater than ever. Your task ahead is a risk at best. The lack of archers in Pains army is his true weakness but he makes up for it with overwhelming numbers of ground troops.
This castle sure ain't no 5 minuter take your time, good luck and enjoy ;-)
