Hey, this is looking pretty solid so far, and I definitely want to keep up with it. I noticed a few things from the start, both good and bad (nothing more than graphical bugs minus the fact I couldn't figure out how to save if it's implemented). It somewhat has an Earthbound feel to it, at least to me. I did a few videos of it, and will do some more later (The thumbnail is temporary right no).
Bugs I noticed:
First, I noticed that the collision between objects vs the player is a bit off, where there shouldn't be an overlapping collision like you have (from the looks of it) and instead a collision detection that doesn't actually collide but still shows it as if the player is colliding, resulting in a smoother collision graphic.
The second, I saw that you forgot or mislayered some of the flowers and grass as they would be on top of NPCs.
Overall, the music and graphics were nice, and I kinda got inspiration to work on an RPG myslf lol.
