Hints for Act IV Scene 4 -
There are way more than four fours here. You'll want to partition them, but how do they link together?
To get the fours to connect, you'll need to get to the base of this Nikoli puzzle.
The Four Fours examples in this grid only run vertically and horizontally. You'll want to write in the totals you get, but they'll need a conversion first. The result should resemble a Slitherlink.
