The confusion resulting from the lack of intuitiveness significantly hinders one's attempts to move.

A successful transformation method would need to get past this tall hurdle of "Transformation Sickness".

Seems like you've solved the problem, since the guys over at the Brainwashing Department didn't seem to experience such problems.

Well, I re-framed the problem.

Wouldn't it be fine if users were "misled" into thinking that there's no "lack of intuitiveness"?

Something like, "You are able to move this form without any sense of discomfort."

Ergo...

If I move this...

Then which arm would I... Wait, I moved my leg?
