Click to jump and earn points. Avoid the crabs' claws!
The crabs are really small because I tried it with them bigger, but it was basically impossible to win. In level 2, the crab's size increases, but it's not a huge increase, but it still makes it harder while still being beatable. Also, this game is harder than it looks, especially if you're playing it on a glitchy Chromebook like the one I tested it on. Good luck!
