Mope.io is a 2D game in which you play in both a terrestial and an aquatic environment. You get to pick what animal youd like to be classified as from either a mouse or a shrimp. The two characters dont differ from each other. Essentially, you move around on land or in water and eat bubbles which represent food. So, the more you eat, the bigger you become. The bigger you become, the faster you can move. Also keep in mind that youre not the only predator. There are some things thatll snap back at you to eat you.
