Just from my quick once over of your ideas, this definitely seems like the kind of game you need to play to fully understand. But if I'm reading this correctly, the idea of creating a character to play a series of minigames that have greater implications/consequences sounds super fun. Reminds me a little of how some RPGs deal with character creation. Torment: Tides of Numenera, for instance, has you interact with a number of stories in the beginning, and the decisions you make in those encounters generate who you are in the rest of the game. This seems like an interesting way of taking that concept to another level.
