Head banging on wall

Moving forward with head banging games, I want to also make a game that you still can pop coins out of a wall but this time, you can customize the wall and yourself.

The Wall
You start out head butting a brick wall but you can purchase with your hard earned cash, different kinds of walls, a wall that looks like a tree, a padded wall, or replace a wall with a mannequin that you can customize (hint: you can make it look like somebody you want to head butt)

You
At the start, you can customize yourself to any way you want to look like, but as you gain more money, you can buy hats, costumes, and weapons.

Weapons
At the start, you only have your head to use, but you can also buy bats, maybe incredible hulk's fist, or a Katana to slash that dummy that uncannily looks  like your better half.

Maybe you can also add sound modules to your weapons to augment or change it's default sound...

And there will be a leader board for the most number of head bangs and a place to share your picture with your wall.

Here is my initial sketch of what i think it will look like.
