Challenge: Create a game in which the penguin has to cross the ice while dodging bobsleds in order to reach the sea on the other side! 1. The penguin can be moved using the four arrow keys. 2. The four duplicated bobsled sprites travel back and forth across the screen, checking to see if they bump into the penguin. 3. If the penguin is touched, the game is over and the bobsled penguin wins. 4. If the penguin reaches the sea, it should celebrate.
