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.
This is crap 0 stars
Theres not to much money after the 3rd level :(
Not so good......at all.
I think that you should make money more pletiful and restore health doesn't completely restore health! If you make a second, (pleaese don't!) don't make the enemies so fast. I hate the human. And it's eay to miss with the cannon. Also I upgraded the cannon but it wasn't any stronger. I'm being really nice and giving you a one instead of a zero like this deserves.
