It is a good idea, yet I wanted to point out, there are people like the idea of seen a MC fighting all her way to the end yet still fail and fall under control by someone. So there should be one or a few critical choices and one final choice. So that player can enjoy all outcomes and passes: a) Break through the hypnosis, b) Willingly give up to hypnosis, c) Battle the hypnosis real hard yet finally commit true submission to someone. The fun is the struggle, the more struggle alone the way of building up the story, the more fruitful the outcome will be for players to enjoy. 'Nothing comes cheap'.
