WOW, today was productive! I actually finished off the overworld maps (including the lead-in to the final dungeon of the game: Akeldama's castle). I made the last not-castle dungeon, too. It's only one level, but it triggers a flashback where you play as Amar on the day he royally screwed up and painted a big target on his back for the vampires to get their revenge (its hard to explain without spoilers...except that I will say it ties directly into an older game of mine, as in I am literally lifting dialogue from that game for this cutscene). In this flashback, I learned both how to change the main character's sprite AND how to hide followers. So yeah, thats a lot.
Tomorrow, I want to focus on the flashback scene. Get various dialogue and animations and sound effects in place. Figure out how to make the map look like its nighttime. Etc.
