I believe I spent over 20 minutes on the church survival section. The first section shown was beaten on the first try but still tricky. I had enough power to do my rage move, or whatever its called, so that shredded the large enemy.
For the church sequence I didnt realise the gargoyle was healing itself and the other large enemies, so I wasted alot of time attacking the enemies. Once I figured out that I had to shoot the boss weak spot when it was healing, that made a big difference. That segment probably still took me over 20 minutes as its tough with everything going on.
This was after forgetting all the controls and moves, after a long break. This one has been in the backlog for a while. Most of the sections are pretty challenging so there will probably be many of them features in the Difficult Gameplay Sections playlist.
