You see, but the lack of choices is itself a stylistic device that can be appreciated as such. If there were choices, the femdom-oriented reader in me would be less happy with this game, because the fact that the hero is forced to go through all those hardships is an important part of the fun that the game provides. If he could "opt out," then I'd like the game less. Now, it is possible for an author to want to be inclusive, and to add choices to the game that lock and/or unlock all kinds of features -- fetishes that are more, or less, common, for instance -- but there is also a charm to a game that is tailored in such a way that something is simply unavoidable. Of course, this game will not be pleasant to those who don't like the unavoidable thing in the game; so they won't like it. But to those who like it, and who like its unavoidability -- it will be just wonderful, and it will be something rare, since most games to offer the kind of option you're talking about.
TL;DR: The unavoidability can be part of the fun -- at least for those who enjoy it. If you don't, it's OK. I understand people who don't like no-reversal games. But I personally do like no-reversal games (it makes the fetish be "inscribed in the structure of the universe" as it were). If I could opt out, it would be less fun for me.
