I recently decided to try to get WSW's top secret ending.
Yesterday, I finally finished collecting all the bonus coins.

But remember what Patrick said?
Now I've reached the puzzle mentioned in the quote above.Patrick wrote:Just know that there might be a little more puzzle and adventure in your future, even if you solved every level, found every bonus coin, and rescued all the Stinkers.
I think I've found out WHAT I have to do, but I have no idea HOW to do that.

I'm not allowed to tell anyone where or what the puzzle is or ask someone for help, but I still have one small question to those who solved it.
I'd like to know many days/weeks/months/years it took you guys to complete this really hard final challenge.
Let's see if I finish it before POTZ is released.
Wish me luck!
