About the Message:

This game is about Anti-Black Racism and the fact that it will not last forever. Those rocks represent racism, and they can seriously damage you. However, the player character is stronger, and the rocks will eventually disappear. 

While this game is focused on one type of racism, its message applies to all its forms.
