Stamina system is slightly painful as is... you get just enough to get you interested in playing, and then you find out you can't even start the next area for over an hour! This is the sort of thing that makes me lose interest...
Useful tip: you can block yourself in narrow passages (and monsters out) with their drops, allowing you to regen safely in hostile territory. + if this helped you too.
A more definitive ending would have been nice, since we're still behind the prison's walls and have no real idea as to what's going on. Are you intending to make sequels?
