Topic, Level "Can you watch this ?", game "Rolling Turtle"

  I have no hints to offer as of yet but I do want to properly give these a go at some point.

  Yeah Goldie is a riddle expert, that's all I can say. I really need a couple hints here.

  I know, I don't know how he does it.

  Gracias Goldie, you are an expert at solving puzzles :)

  I can't seem to figure out the decoder.

edit: nevermind, excellent series by the way.
