It is a great concept for the last stand theme where the father protects the daughter with his life.
I especially loved the music and sound. It gave a sense of fear and urgency with that heartbeat-like sound.
Loved animal sounds before they show up to prepare for the attack.
This would be much better in terms of dark/night background.
It took some time to get used to the mechanics, and it seems like the attack works only when the rock hits the head, not the legs.
Great Job on your submission :)
