If you were given the tools needed to make a video game what would it be about?

I always wanted to make a game in which you bake cakes and deliver them across the levels to the princess who would then eat the cake and progressively get fatter as the game went on. Then at the end there would be a huge plot twist: the hero would have a moment of realization because he made the princess so fat he doesn't find her attractive anymore, then he goes home.
