Got the fourth map made (and added a cutscene that plays when you interact with the body), then went back and made some modifications to all the existing maps. Switched the chests to a smaller-looking sprite, changed the shop building sprite, fixed dialogue beats, modified enemy stats, added some signposts throughout the world (mostly to warn people when they're close to a boss fight), and even added an Inn function to the shop (although I'm not fully happy with the sprite yet, still working on that). Considering how little time it takes to actually add all of that, its pretty amazing.
The hardest part has been modifying combat. It just feels like everything is either overpowered or underpowered, and I'm having trouble finding the right balance. That and figuring out the story, because I kind of have an idea on how I want to end it but no idea how to actually get there.
Main goals tomorrow are to set up the next boss fight and to make sure the boss fights say "defeated" at the end instead of "slain." Because I do want them to come back in the final section. Spoiler Alert: I want them to be regular enemy spawns in said final section. I think that would be cool.
