Moby Dick / Diver

Moby Dick / Diver are two arcade games released together for the VIC-20.

In Moby Dick, the player controls the titular white whale as he tries to gobble fish in the ocean. The player must avoid large icebergs and boats which shoot harpoons towards the whale. The player gains points by eating fish, and can destroy whaling vessels by ramming directly into their bow. Bonus points can be earned by moving into lagoons when they appear. The player starts with 3 lives.

In Diver, the player controls an underwater diver who tries to gather all the items on the screen while avoiding jellyfish, weeds, rocks, and other underwater dangers. The player has limited oxygen to complete their task, and touching anything will result in loss of a life. There are 2 levels of game speed, and the player starts with 5 lives.
