Remix this code and add blocks to the shark sprite code to 1. Create a variable score and set it to 0 at the start. 2. Increase the score when the shark and fish touch. 3. Add code to check if the arrows are being pressed and move the shark in the appropriate direction. extensions 1. Start with more than one fish (see the fish code and clone more fish). Delete a fish when it is caught by the shark. 2. Add a timer - game is over when you catch all the fish. How quickly can you do that!
