Take underwater photos, and then surface to review them. The bigger and better the fish, the better the picture!
Ocean Explorer was made shortly after my trip to Hawaii in 2007 with my dad and sisters. All the fish and the turtle seen in this game are copied from what I saw on my dive trip! The gameplay is similar to the game Pokemon Snap, in that bigger, better pictures will allow you to move on, and that was part of my inspiration for this underwater game.
