I don't possess the right skills for such fast paced action. I always get scared when the Grinch-Monsters attack me and since dodging doesn't work, I run out of gifts because of frantic firing around...
Tried several times but those monsters always got me. Took me like 4 tries just to get to the gift bags on the first screen to the left and then I died again going north. Really challenging
Maybe an easy option for the casual gamer, where you can fire at least through the walls and the monsters go a little slower?
All in all you did a really good job!
