Wonderful aesthetic. Getting a good atmosphere is hard, and you did great on that department. While I have yet to finish the second act, I still want to come and leave a review.
Probably the only real complains I have are:
-sometimes it's not clear what tiles are you can walk through. I often get stuck in the enviroment
-during the dialogues, you could add more obvious clues to show who is currently talking, since both portraits are shown at once. (maybe something like someone's portrait darker when they are not talking).
on a sidenote, I love your enemy designs, good stuff.
