As someone who's working on their own RPG right now, this was pretty inspiring! It's already helped me with a few things.
The intro to the game already had me liking it, because of the little fire mystery it set up. Then the shadows just being a cool concept in general made me run straight into the first one of the game expecting a fight... I uh, I died but I figured it out later...
The fairies and mirror world were pretty intriguing too. It kept me coming back to see if there was any new dialogue I might've missed before I proceeded, and I also liked the art.
Very good job!
I'll keep that last part in mind... and maybe since you're like a professional you could give input when I release my RPG? Because I want it to be good... also, In the game I did notice the players sprites don't really match with the tiles... like, the resolution is higher for her, is there a reason for this?
