Very interesting! And clever game design. Focusing on the many small annoyances and problems allowed me to empathize with your situation, despite the fact that I still can't imagine how it must feel to be born in the "wrong" body. Still the concept is less "alien" and "weird" than before playing (and thinking) about it.
I also don't want to critisize the simple gameplay. It didn't provide challenge or fun as much as it kept me in the flow and helped my usually erratic attention to stay focused on the topic. A job well done.
All in all a great example of how games (as a media) can provide more meaningful/deep experiences than the usual flash-game even aims for.
