OK, so I’ve completed Chapter 4-4 (that’s all of 4 done now), and I’m out of the castle. There was a huge Salazar statue that (as suspected) “came to life” and chased me, then there was a climb up a huge tower, complete with Donkey Kong homage, and finally a fight with Salazar and his “other” hand man, who combined with a big slimey thing.
Well, I say a fight, but in reality it was easy. I stood still, went for the weak spots with my Broken Butterfly, and after about 6 hits he was dead. I didn’t even get hit. Or nearly hit. In fact, he didn’t even appear to attack. Amazing.
After all that, the woman in the red dress (Ada?) appeared again and gave me a lift across to an island for Chapter 5-1, some of which I played but died before getting to a save point.
