This has some phenomenal writing, great art, and I really enjoy the premise.
Mechanically it feels like a pretty straightforward reskin of ETR to incorporate new fiction. But the details are where this one shines. Most of the work in creating new stuff feels like it was very focused on the fiction & narrative side of the game, rather than adding new game mechanics. Personally, I think that's just fine. Creating a well polished game out of a reskinned engine and making it feel totally cohesive is really tough, but I think this submission nails it.
I particularly like the encounter design. The encounters themselves feel unique and true to setting (they're also extremely well written and witty). My favorite encounter is Pity Party. I really enjoy how the description evokes imagery at the table. I feel like these prewritten encouters really give the players something to work with at the table. The enemies are varied and interesting (and again, very well written and humorous). Including loot for each one is definitely a nice touch, as is the random equipment table in the back.
It's clear that there was a lot of effort put into making this feel like a useable game. Everything seems very well rounded and well executed. Amazing job!
