You are the ball. Run the program and chase the octopus, but avoid touching the crab or the shark. Earn extra lives and gain points. But all in all, enjoy! Touch the fish for extra lives; you win if you have at least 20. You lose if your score goes below 0.
Just a brainwave, and a bit of brainstorming. Inspired after visiting the California Monterey Bay Aquarium, and created a project based on it. Have fun! Refill lives by pressing space.
