This is super poetic. I really like the shifting fonts! there are certain passages where all of the font looks the same, so it takes that extra bit of searching to find the next link, which could be challenging in some other games maybe but I think it works really well with the tone of this piece.
At the ending where the Oil Seller passes away, it could be interesting if going back to the beginning presented a different version where there's only one character / only the option to be the frog seller.
This is also a wonderful example of cultural preservation through digital art :-) great work!
