Hi there, glad to see you're enjoying the game so far. I was kinda worried the tone shift might be too abrupt at times. The Amber scene in particular was one I was concerned about but I felt it was important to leave in to convey that the world in this story is a rather grim one but despite this people will still try to do good, as well as establish some of Amber's motivations.
With Amber's character in general the tone shifts are actually supposed to be part of her personality, the idea being that she's constantly switching between thoughts and will often have rather dramatic shifts in tone during a conversation.
As for your question, no I am not Sulcate but I am commissioning Sulcate for this project, definitely no chains or basements involved.
