Once I really figured out the controls it was easy to prevent my human from getting hit. To actually help it to score I feel that changing direction of gravity is too cumbersome. I think it would help the gameplay if you could, for example, use left mouse to pull a snowball downwards and right mouse to lift it upwards.

Some sound and music would be most welcome.

The game was fun. It was actually pretty difficult, or maybe I just sucked, haha. It would have been nice to be able to change gravity by just holding down the button instead of having to spam it to quickly change the gravity.
