This is pretty nice. It can be pretty hard to pull off something that's more narrative focused for a gamejam due to the limited time but I think you've hit a sweet spot here where it's not overly complicated but still has a bit of deeper meaning behind it, at least that's what I felt after getting to the end.
I quite liked using both the 2d and 3d mix, it felt like how in an RPG you tend to get stylized overworlds to explore that are separate from the actual areas.
