Just read this piece that folks might be interested in. The game is set in a town where the residents all turn into cats at night, including the female protagonist.

Whether there will be any process remains to be seen as it is still in the concept/funding stage. There's some concept art of the main character in both her human and cat form, but not much else so far. But hey, the guy's got some weird games under his belt, it may involve some on screen transforming.
