O seu Canvas precisa receber o foco para poder tratar os eventos de teclas.

Edite o seu initFrame():

public void initFrame() {
	frame = new JFrame("Game");
	frame.add(this);
	frame.setResizable(false);
	frame.pack();
	frame.setLocationRelativeTo(null);
	frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	frame.setVisible(true);
	requestFocus(); // após abrir o JFrame, focar o Canvas
}
