Depending on your genetics, it may not in fact be your fault, or anything wrong with the games. For example, those on the Autistic Spectrum tend to be difficult to hypnotize. Nobody is quite sure as to why, but that much is consistent. I would be shocked if there were other conditions that made one difficult to hypnotize.
We're sorry to hear that, MrLama! In our opinion, it's less that certain minds are difficult to hypnotize, and more that different minds require different kinds of hypnotic inductions. While we do our best to blend together multiple induction types in our projects to cast a wide net, we haven't yet done much with confusion inductions, which may be more up your alley. This has been an oversight on our part which we'll do our best to correct in a future project.
