Art: I will say this art style evokes a sort of Ozymandias "Look upon my works ye mighty and despair. Nothing beside remains" feeling, which is exactly what I would want from an Ancient Myths trifold. 

Writing: I'm guessing this was meant as a toolbox from the spartan writing. Lots of consideration for how much space you had without shotgunning it on the page. The instructions are concise and easy to understand, and I'll more than likely be using this in the future.

Game Design: As a dungeon maker? Really convenient, plenty of roll table curiosity. Easy to work off of one the fly.

Theme: For the theme, I do have to give points for integrating classical dungeon vibes into the dungeon maker, and the roll tables (love the list of inspirations)

Layout: While I do enjoy the two sides of the trifold separately, it does flow into each other a little choppy. Like one sort of setting suggestion and one toolbox for dungeons, leaving it as a sort of starter for the flame. If that was the intention, mission accomplished. If it wasn't, there might need to be more connective tissue between setting to utility.

Utility: As a toolbox this is insanely good for pickup and run. As something to generate lore? It's a good start, and good for initial thrust, which feels like the intention

Favorability:I'll say it: this grabbed me immediately. Even though it's labeled for Mothership 1e, this feels like WBR level utility.

Overall this entry is sick as fuck, and the only real critique I have amounts to minor polish on an already great trifold. I will be putting this in the proverbial Warden utility belt as an Ol' Reliable.

Art: Cover art will surely be Best in Jam, and the overall visual impression is very good.

Writing: I think going vibe-heavy for the scenario hooks and focusing on clarity for the interior was the correct choice and you did well with both. The Suneater scenario is by far the stronger of the two.

Game Design: I'm of the opinion that entrusting the dice with designing an adventure for you never goes the way you'd hope, but there are some nice tricks here. The solution for quickly generating a floorplan has broad utility, and using an "oracle" table to put the actual design decisions back on the Warden with vague prompting is a good call. Better than the loot and encounter tables, which will push the Warden in more bland and generic directions, which is inevitable when trying to use a single pamphlet to design a wide variety of scenarios. I think the system for determining when you reach the goal is unnecessary in that the Warden could just choose a number, and too high-variance... e.g,  a challenging scenario has a 15% chance of ending on Level 2 and a 15% chance of ending on Level 10, when for the sake of session planning and pacing, you probably want the range to be +/- 1 or +/- 2.

Theme: Well-implemented in the Suneater scenario. For Consumptive Curiosity, the Mouth is something about which myths could develop, but I'm not sure I'd call the scenario mythology-themed.

Layout: Straightforward and effective for the most part. The only weak point is the table. The lack of row divisions (or alternating shading, etc.) combined with having the Yes/No/etc. answers in the same color and font as the numbering leaves the whole thing kind of lacking structure and not looking very table-y. It's not that it would be hard to locate the right entry when rolling, because it's big enough that you're not going to lose your place... but its form doesn't really follow its function. The design doesn't tell you how to use it without reading the text.

Favorability: I love the art, the Suneater scenario, and the floorplan generator. Everything else, I would probably pass on.

Looks incredible from start to finish and the two scenarios presented are intriguing right off the bat, but could be worth condensing to make room for other stuff. Ruin generation mechanics are solid, I would love to see more tools to help GMs fill those ruins and engage their players. All in all this is a cool tool kit with a lot of potential that looks amazing, fantastic work.

I love the design and styling on this one; very slick!

I really like this! The procedures are fun and the oracle table looks like it would be fun to use. 

I think some minor tweaks could make it more user friendly: 

I had to read the Ruin Engine procedure twice before I understood it. I think putting a little label explaining that L0 rolled a 5, then a 3, then a 2, then a 6 would make the procedure much clearer. 

The d100 to determine stairs is confusing to me, I think an example of how exactly the roll relates to the map would help. 

I'm also not sure what "set the probability that the objective will be found by the desired difficulty of the scenario" means. What does it mean that an objective has a 30% chance of being found and how does this interact with or relate to the PCs actions?

I have read Roadside Picnic, but don't remember what "mosquito mange" is, I have not read the other referenced works. I think these references may frustrate more Wardens than they inspire.

This is really unique! I think since it's more of a system for running depth crawls it has to be judged moreso as a warden's tool than as a self-contained adventure, and in that category it really shines. Ideal for any GM who likes rolling up his sleeves and building something to challenge his players!

I really appreciate the artwork; it is visually strong and an excellent choice for conveying the intended mood and aesthetic. The artists should be very proud of the work produced. I would, however, have liked to see some illustration work incorporated onto the exterior pages, even if only in a subtle or minimal way. Additionally, I found some of the maps slightly difficult to read at times.
