Very, VERY good.
Although it feels more like an interactive movie, I think you did a brilliant job on this. I don't know any trans people, the concept has always been one thats kind of strange to me, but I can imagine that having elements of multiple genders is certainly something which opens up all sorts of bullying comments, and frequently I've imagined that living life trans-gender is difficult, but this game in an incredibly artistic way is almost like education for people like us. I've always imagined it would be difficult, but the way you portray it in this is such a life changing thing due to so many things changing; everything from physical feeling to the way society views you, to how your friends and family treat you.
You did an excellent job with this game. Gameplay wise, it's not the best thing I've ever played, but in a way this really isn't the players experience with a character as much as it is the writers experience with the player, which is not something I've seen before, really.
The artwork is nice, albeit simple to some degree, but the metaphorical imagery is certainly something I enjoyed (like literally bieng a spy, hiding from society), and the soundtrack is excellent, fits in perfectly with the feel of the game.
Very nice of you to share your experience with the Newgrounds community. Even better to see positive reactions to it. Congratulations on bieng frontpaged, I feel this game was well deserving of the praise its been given.
