Found it! I made God's shovel... What about broken keys? I have found only 2!
I had two key pieces in my inventory prior to this update.
There is a third to be found in the "whirlpool" room you start the new update in, but I haven't found any more.
That being said, if someone could let me know if/how it's possible to obtain the key behind the wall next to the Doctor's Office, that would be amazing, since I can't seem to find enough keys to unlock all the available chests at the moment.
It should also be noted that there are a series of switches to find now; once you locate all four, a standard chest key is dropped.
Edit: There are also four Compass Pieces to be discovered, which the game gives no direction on how to find; the Compass Pieces, when combined, will show you the hidden switches you need to press - although you'll need to find the switches on your own.
