Eat as many worms as you can as the timer ticks up. Avoid the sharks.
Press space to stop, move with the arrow keys, and hit control to reset the room, enter to move your fish character to the starting place.
The point is to see how many worms you can eat in as short of a time as you can, the standard being 100 ticks, seconds, or whatever they are; then when the set time runs out, someone else plays to see if they can beat your score.
Enjoy!
