Initial Comment:
There seems to be a bug in the scene where monks chase Robin with rocks right before the end (scene 710).

Robin is supposed to be escaping from the monks in the monastery, who throw rocks at him, while he's climbing down a wall. In ScummVM, he can't climb down the wall. Also, the monks only throw one rock, which goes off screen (not down the wall, and it never bounces on the wall) and seems to be falling forever. Thus, the game is effectively stuck.

I am not sure what is wrong... I tend to believe that this is a pathfinding problem, though this is just speculation. This is likely a regression, as people that the game is completable in the past. It might be caused by the recent changes to kInitBresen/kDoBresen. I haven't bisected to check which commit broke it.

Here's what it's supposed to look like:
