I really did not find anything special about this. It's mostly because it's a bit too repetitive. You need more of a variety of enemies coming towards you. I guess I can't really say that there's anything wrong about it. It isn't too offensive or anything. The graphics and music are just mediocre. It's still better to have something mediocre than something bad.
You were a bit late into Winter for this one. Then again, winter has most of March in it. Why is December considered more of a winter month than March? I was afraid it was wrong for me to hit the birds. They don't have as cool a "death" as the snowmen.
