I love how I kept thinking this was about the bird until I actually opened it up and read it [the clearly referential graphic design for some reason didn't click, haha!] a very lovely shout out and side adventure for those who get the reference!
It might help in terms of formatting to put the maps next to the relevant scenes, I found myself getting a little jumbled up and confused trying to read and imagine it [I kept jumping between picturing playing a Mario game and picturing myself at an RPG table trying to explain it to my group lol] before I realised there was supplementary material to help out!
Also you should probably put the bit about the having three failure restarts before properly perishing towards the beginning of the side quest, as there's a real chance the DM/GM won't read/forget what the aftermath says when running it, and then will end up messing up that aspect while in the middle of play, not having gotten that far.
