This was nice to play because it allowed you to cover a lot of ground with your single snowball. It's great fun to just watch it go along. For those of you who do not know, you can run into the other pieces of snow (like the snowmen) to become bigger. The best part is how terrified everyone looks as the snowball gets bigger. It is also fairly easy to get a score. I am glad that you pointed out that this was a game in its own right and it is not appropriate to call it a copy.
One good thing was the simplicity. Everything is detailed in such a nice way, but the only problem is that everything does look a bit small. I guess that makes the game easier, but it makes it a little weird to look at. You should also put in some music, but you did make the other sound effects wonderful! I love how everyone that you absorbed falls out when you hit something.
