Very fun puzzles!
also in chapter 3 there's an error/miscolour.
[BW|W|G|W|W]
[W|W|OY|OB|OY]
[OY|W|OB|BW|PY]
Was printed as
[OY|W|O|BW|PY]
*B=blue|W=white|G=green|Y=yellow|O=orange
Thanks, good catch! I deleted the orange in the Google slides and there was an OB under it, so I guess it snuck in there somehow while I was copy and pasting :T
Lovely username by the way!
