Yep, unfortunately. At first, when Rainces said he made a walkthrough, I'd hoped it would be for the full game so far, since apparently the in-game hints don't seem to work for some. Maybe the following advice can help, maybe not.
General Advice:
If you try something and it doesn't work
at all, don't do that thing again. If you try something and it
kind of works, pay attention to what Bobby thinks and what the blue circle in the upper right tells you.
Here is a lengthy example where I applied the General Advice from above. Everything in
bold yellow or
underlined italics is a clue on how to continue progressing.
This is exactly how I figured this part out on my own. Hopefully that will help others moving forward if the in-game guide isn't enough.
