If you read through it you would see that the mini-games are referenced and described, the reason every single detail of them is not written down is because:
One, it is due to change depending on coding restraints and time,
Two, as you would know if you read it that the document is the first draft, i never once said it was completed.
Yes i was looking for creative criticism, but that is more than what you wrote which in basic said "This is not a design document, it is just ideas."
Although if you think about it that is what a design document is , it is ideas which you want to make into a game.
Also the mini-games are detailed enough to get a drift of what they are, for example the lessons are mini-games. Also there will be things like quidditch, which i will not write a detailed description about as the game is a fan game and intended for fans, therefore they will know what qudditch is.
