Dave the Diver has you scuba dive (shocking I know) to hunt for fish to support a sushi restaurant. It's a great game with obvious upgrades to allow you to withstand greater pressure depth and collect/hunt more fantastic fish for your restaurant.
But this game suffers a bit from .. over production? Not only am I managing a sushi restaurant, but I have a farm, a water farm, a fish farm, a mermaid plant farm, a second restaurant, a social media account, I'm taking photos, collecting playing cards for some reason, doing "green ocean" missions, hunting rare fish, racing seahorses, playing cards, I'm researching for a scientist,... oh, I'm doing missions.
Maybe if these additional features had been rolled out after I was done with the game as other ways to play, or just presented in a way that left them as less urgent than the main quests ... as it was, it was a bit overwhelming. DNF.
