Watching Thimbleweed Park "let's play"s is painful

I can’t pinpoint a specific example but I remember that several Lucas adventure games have used this technique in the past and, yes, it might be perceived as a spoiler if the only option kept is an important piece of information.

Maybe keeping both the important option and a few unnecessary ones might be a simple and viable solution. Actually, I think that some games did exactly this.

If you are such type of player like this Let’s Player (e.g. hectic mouse movements, prone to overlooking stuff), then maybe you should consider playing such game genres together with friends.
It’s often more fun and you have another pair of eyes often preventing those specific situations.
