This game seems easier than I remember.
I always loathed the part where you use the cannon to get into the castle because of those damn catapults, until I realised you can just shoot the barrels next to them with a pistol. I also remembered there were more enemies running after you at that part.
And then there is the part where you control Ashley, which was always the scariest bit of the game for me because you felt so vulnerable. I thought you couldn't kill the monks, only slow them down, but there are actually more than enough throwing lamps to finish the job, and a shortcut I previously missed too to completely bypass the first one.
