Getting low ratings really annoys, and most of the time you cant even do anything about it. Its getting really hard to score at times, and if you miss the goal, what might happen, it tears you down. Real players cant always score, they miss too, and noone blames them. If i were a player i had 26 goals on my own, like i have here, i would be a superstar and noone would ask how many times i missed the goal.
40 is really tricky, i got past it by only building undead tower near the entrances, so the first hit would be a hit by one of them. The key was the use of the special abilities, fear, freeze and disarm. Fear and freeze are selfexplaining, Disarm makes the creeps lose all abilites. While freeze is my favorite, because you can easily kill them, followed by disarm, making them not use their vanish, fear is least helping, they still use vanish, if your lucky they start at your dmg highspot again after the fear.
Past 40, beware of 46, there's ninjas again, i had to meteor them.
This way of getting a brilliant in 15 worked several times, i made some tries with it... Took quite some time to get a working tactic for this ;)
