Enable Tux to look up

[Ordoviz]

When the player presses up Tux should look up. This gives the player a visual hint that pressing up has an effect in the game (carriable objects can be thrown upwards). Apart from that, it’s always a good idea to give visual feedback when buttons are pressed. And it’s just fun to see Tux dancing when you press a bunch of buttons. Here’s my wishlist:

• New sprites: Tux tilting his head back.
• The light cone of the earthflower should point upwards when up is pressed.
