Well to be honest I play with a friend, and sometimes we're both : Yeah, no clue what to do here, so we just go for the solution.
It happened 2 or 3 times in the course of a 80 hours gameplay, which is perfectly fine for us, we're not so much for the "adventure kind of game where you try every combination possible".
We're pretty much where you are now, and I think we're getting close to the end, so enjoy the final hours, hopefully we will.
