There's a phone app that basically works like the X-change pill stuff.
Impression (v0.1.2):
Very barebones, the game play is work for cash, do phone quests for TF points. The game will crash if you hit "no" to doing the quests. As of now, there's a slutty nurse with optional lewds, and a "girls" slumber party with non-optional sex. It mostly works as a proof of concept for the game structure and introducing the NPCs.
I was expecting something with more subtlety to the transformations, but it's pretty much a magic spell that alters your character's looks and personality completely. The game would crash if you try to transform yourself.
M2F/genderbending is a turn off for me, you can start the game as a female character, but it seems likely that it's going to be in most of the other character's storylines even so. The slumber party hooking up not being optional makes me think that a lot of other lewds won't be optional either.
