No Power to Sorcery trophies missable?

[Motherboop 8]

I believe I missed "No Power to Sorcery 3", as I just got 4.  When I attempted to backtrack, the path to cream puff mountain was inaccessible.  Any way to back track later down the road, or do I need to restart?

You will be able to backtrack later on.

So I found this one to be annoying as well 

 

when you travel down “The Path to Creme Puff Mountain” go the end (about 2 screen changes) there is a hole just before you pass through to the next area jump down it lean to the right when you do you will land on a rock jump forward to the next platform and you will see the poster directly behind you.
