This video game adaptation of Jaws appears to be based on the second half of the movie of the same name, which focuses mostly on finding the shark and killing it. None of that boring stuff such as the mayor refusing to close the town for the summer holidays despite warnings of potential shark attacks.
In this run by SpaceColonizer, the attack level is upgraded to 3 to kill Jaws in a single encounter. Luck manipulation is used to get encounters in the shortest time, and a purposeful death is used to avoid a bonus scene. He also manages to save 2 seconds over his previous run through rigorous optimization.
