Expanding on my idea
A fairy tale character who has amnesia goes on a quest of self discovery. On the way the player will find a number of items which could be the key to finding out who they are. within this level will try to provide some mortal lessons while piecing together who you are. In essence the character is trying to find out who they are by interaction with other fairy tales.
The player starts off in a Forrest in plain sight there is a village and a castle it is up to the player at that point to go exploring this world. The environment shouldn’t look too familiar at the beginning of the story. The visuals should no way imply that you are in a fairy tale until the end.
In the world they will be able to find various objects to access various places in the level. These objects would relate to the fairy tale in question or they could not.
An example of this would be that the player would need a spoon to eat the porridge to interact with the three bears house. However the player has a basket of goodies the player would be the same character as the player would not be able to interact with the environment. On the other hand if the player went to grandma’s house deep in the woods the player would see a wolf in bed that After the player got out of the house the player would turn in to little red riding hood. By the player turning to little red riding hood the charter would be able to finally learn who they were.
In this game/level you could experience 3-4 different tales but you don’t have to experience the one fairy tale it could be you could have a mix of all 3-4 and create your own fairy tale.
So in essence the player is determining who they are by the stories they choose to undertake.
