We're all eagerly awaiting a next update, me included. Fortunately FF5 posted about some progress, so to answer a few questions:
Well FF5 mentioned the transformation part is being worked on now, so I hope we can expect to see it soon, dunno if your pics will be it it though..
I guess the next question is your answer?
If I remember correctly you need to progress just a little more. Something to do with a key you need to obtain. (don't want to spoil)
EDIT: should have read your post better, you already have the key.. Maybe
_FapForce5 can shed some light?
