It feels like some one forgot to read a note which lead to some missable trophies. If you are not following a guide from the start of the game you can probably not succeed to unlock everything. Some areas locks up and you can't collect all playing cards and the strum just disappears without any warning.
Why is this bad ...
- Punish a player without warnings.
- And you shouldn't need a guide which 9 times of 10 spoils the plot.
