Crab Cakes is a game where you get to take on the peaceful life of a fiddler crab. Your hobby is strolling through the beach collecting various trash items to sketch in your notebook. 

Sometimes you are hungry and so you must scavenge for food. But, as expected, life on a lovely polluted beach comes with its perils. You can never be certain what toxins lerch in those scrumptious food morsels. Eat at your own risk.

Fill your notebook, fill your tummy, hope you don't die.

(The preview character is a reference to Animal Crossing: 18 colors)

(In Chinese literati culture, painting crabs among long blades of grass is a popular subject, this is my take on it)

edit: pulled out two shades of blue, and fixed some empty on the Crab sprite. Now its 18 colors in the detail image.
