Super Crab

Story:
You are a crab who has wandered far away from your home. You are very hungry, and would like to eat worms. However, you're not the only one whose hungry! You must survive until you have eaten ten worms. Don't worry though, you're actually Super Crab!

Controls:
Arrow Keys- Move and control the Crab.
Space Bar- Activate your shield.

Animals:
Lobster- A lobster runs at a decent pace, and will attempt to eat you. Additionally, it will get faster over time.
Turtle- A turtle is very slow, but it will eat both crabs and worms.
Newt- A newt is small and nimble. It will not harm crabs, but will devour worms.
Worm- Worms will spawn over time.

Super Powers:
Speed- Every time you eat a worm, your speed will significantly increase. This will help you evade lobsters and turtles, but it also makes you more difficult to maneuver. If you see a red aura around you, you are currently in "Speed Mode." The effect will wear off over time, but if you eat another worm, you will activate your speed again.
Shield- Press and hold the space bar for a temporary shield. When your shield is activated, you will be invincible from lobsters and turtles. However, you can only use it for a limited amount of time, and you cannot refill your shield. If your shield is activated, you will see a green aura around you.

Scoring:
Your score is based on how much time it took you to eat ten worms. If you were eaten by a lobster or turtle, then your score is automatically zero.
