The concept is very unique, and I liked it.
Graphics/animation could be cleaner and improve more.
What I didn't like is that there were flaws in the gameplay. For example, it was very hard to beat Rudolph because he's small and you had to get a really really precise angle to hit him. Snow queen and Superdude were easy to hit though. Perhaps if you evened out the playing field and add attributes, like Snow Queen and Superdude could afflict more damage, and speed of snowball making and such.
However, I did find this game very enjoyable, and humorous. Grammar and English typos should be fixed (that kind of thing makes me mad). Perhaps if you improved on it more, it would be a very fun holiday game.
