// CONCEPT: one of three doors will have a car while the other two have only a goat
// randomize a winning door each round, let the player choose a first selection
// reveal a goat door and allow the player to keep or switch their selection
// based on the Monty Hall problem from Let's Make a Deal
//void draw_goat(Canvas* canvas, int x, int y) { TODO }
