We have the instructions on the screen, but to clarify, plz avoid the mean pufferfish. You have to eat the shark by following the mouse pointer. You are the fish. It's a tiny bit glitchy, and if you get to score 100, you will win! If you're on score 0, you lose :( You gain 1 point for each shark you eat, and you lose one point for each time you get spike by the pufferfish.
