In this game players would control a swimming cat with a snorkel, who would need to catch as many fish in the snorkel as possible. This would funnel them into the cat's mouth, creating a fully optimized feeding system. The game would be played in a side on view, showing the player's cat along with the nearby fish. Controls would be similar to the water levels in Super Mario games, with the player slowly falling to the bottom of the level when not pressing any buttons. The player would need to maneuver below a fish, and rise up beneath the fish in order to funnel it into the snorkel. The cat is only able to eat fish while above the water, however, as otherwise the cat would drown. The more fish the cat has in its snorkel, the harder it would be for it to breathe. This mean that the player would need to rise to the top, as they need to eat their collected fish and gain more air. Eating fish would fill the cat's hunger meter, however it would also make the cat fatter. This would mean that the player would fall faster, and rise slower. This would continue either until the player's cat drowns, or the player reaches a certain place in the hunger meter.
