In the 'untitled goose game story', the goose is the star. But the villagers also play important roles as they are the ones the goose torments. There's the old lady who might be knitting and gets startled by the goose, the postman who has his letters knocked over by the goose, and the farmer who finds his crops messed up. All these characters together create the comical world of the game.
The main character is the goose, of course. And there are various villagers like the gardener, the boy, the shopkeeper, etc. who interact with the goose.
The key character is without a doubt the goose. It's a mischievous protagonist that drives the story forward with its naughty actions. Then there are the villagers. The young boy who is always on the go and gets his plans disrupted by the goose. The shopkeeper who has to deal with the goose rummaging through his store. And the gardener who is frustrated when the goose messes up his carefully tended garden. They are all integral to the story as they react to the goose's misbehavior.
The village dog could be a main character too. It could be constantly chasing the goose or getting tricked by the goose into chasing its own tail. It might also have a soft side and end up befriending the goose in an unexpected turn of events.
The goose itself is obviously a very popular character as the main troublemaker. People often write about its mischievous antics in great detail.
The 'untitled goose game' is about a naughty goose causing mischief in a village. The goose goes around stealing items, honking at villagers, and generally disrupting the peaceful village life.
One interesting plot could be the goose forming an unlikely friendship with another animal in the village. For example, the goose and the cat team up to prank the villagers in a more elaborate way than the goose could do alone.
A simple plot could be the goose getting lost in a new area of the village that has never been explored before. It then has to find its way back while causing chaos along the way.
I'm not sure who the main characters are in 'untitled love story' as the title gives no clue about that.
A crossover with Minecraft would also be cool. The goose could waddle into the blocky world, disrupt the building projects of the players. It might steal their resources like diamonds or iron, and peck at the creepers just for fun.
The geese themselves would be obvious main characters. Each goose could have different traits, like one being the brave leader, another being the cautious one.
Since I don't have much information about this story, I can't say for sure who the main characters are.
First, decide which universe you want to crossover with. Then, think about how the goose's personality and actions would fit into that new world. For example, if it's a crossover with a fantasy world, the goose might be seen as a strange magical creature.
