I'm sorry, I don't know the specific 'My Little King Story'. Maybe it's about a little king's adventures, like ruling his kingdom, facing challenges from enemies or making important decisions for his people.
It could be that the game doesn't fully support the PS4 controller's default settings. Try adjusting the sensitivity and button mapping in the game's settings if available.
In Little King Story, the king typically focuses on ruling and adventuring rather than getting married. The game doesn't have a marriage option for the king.
Dungeon Village is similar to Little King Story. In this game, you are responsible for building and managing a village that attracts adventurers. You need to develop the village, assign tasks, and deal with various events, which shares some gameplay elements with Little King Story. Another one is Majesty. You play as a ruler and have to manage your kingdom, build structures, and send out heroes to complete quests, much like in Little King Story. And then there's Tropico. Although it's more about building a tropical island nation, the idea of ruling and making decisions for your land has similarities.
I'm not sure specifically which 'Dolphin Little King's story' you are referring to. There could be many fictional stories about a dolphin king. Maybe it's about a little dolphin who becomes a king in the underwater world and has adventures like protecting his pod from predators, finding new habitats, and making friends with other sea creatures.
The 'new little king's story' might have updated graphics compared to the original 'little king's story'. It could also have new levels or quests. Maybe the gameplay mechanics have been refined for a better player experience.
