I love the idea of the snowball and I think the sprite is super well done! I really like how it moves from side to side depending on which arrow key you click.
I also really like the fact that we can speed up, I thought that was a nice touch.
Sometimes I feel like I cant see where I am going to fall, so having a more zoomed out view would be really helpful and would make it easier to get through the levels!
Otherwise great job!
