Destroy the Village

You are the lord of darkness, and your goal is simple: wipe the village off the map before time runs out. Villagers hide in their houses while iron golems and diamond-sword heroes guard them. Release monsters from the edge of the field and lead them into the attack. You command five fighters: a zombie with a huge health pool that chases villagers; a fast, cheap spider that swarms in numbers; a skeleton that shoots defenders from afar; a creeper that runs up to a house and blows it apart; and a mighty dragon that scorches a whole block with a cone of fire. Souls regenerate on their own and drip in for every kill and demolished house — spend them wisely on who to summon. Each level the village grows larger, the defenders multiply, and time gets tighter. Dozens of levels across different biomes: blooming meadows, scorching deserts, snowy lands and burnt savanna. Your progress saves automatically. Can you raze every village to the ground?
