I'm a fairly new DM (1 1/2 years of a weekly 5E game). I had to put a bit of effort into enticing my players to try a new system and then more time into making the intro/hook here appeal to them. This may just be a difference in style from what they are used to.

The maps were easy to follow with limited information provided about each room and bolded text that could be read aloud or paraphrased to players. This is in keeping with the style of Shadowdark from what I know so far but for a new-to-this-system DM I felt I needed a bit more help. I lost the tone at several points using the flavor text. Usually I telegraph to my players a bit strongly on hidden rooms and traps as my players are cautious by nature and I didn't want them burning through all their torches searching but with several rooms they became fixated on the fact that there was nothing to do/find and wouldn't move on.

I'm not sure how long an adventure like this would typically take a group and the example play time wasn't listed anywhere. We played for a few hours but didn't finish. I don't think I understand the pacing of this adventure within this new system so I didn't feel I had the right feeling of pressure keeping players striving forward and we didn't have enough to interact with ... I think this might have been me not feeling comfortable in the new system. My group didn't like the kobolds and bandits and I couldn't really provide a strong reason for their presence. If I were to run this again I would change those out for something closer to the other monsters in other parts of this adventure to run it as more of a horror.

I fully admit that much of my difficulty with this was due to my lack of knowledge/skill in running Shadowdark rules as I only had the free quickstart guide. I think if you know more about it you will have a good time with this adventure. I will keep it in my pocket and maybe when I get the full rulebook I will be a better DM for this.

This is a great resource for anyone wanting to write their own materials or just to help finesse some published adventures. I stepped into the role of DM about 1 1/2 years ago and have been running a weekly game plus a couple one-shots per month. I've relied on other's materials for those but have found as I become more skilled and comfortable in my role that I want the freedom to move in my own directions; I just want to do it really well so my players are happy. This resource was recommended in a video on how to create a strong adventure so I came to check it out. It is worth every penny to me. So much so that I also purchased the book from their website and am anxiously awaiting it.
This isn't just a book of role tables but those are what I have already spent time diving into. I don't believe I could simply roll and an adventure would magically create itself but the inspiration and ideas really get your creativity flowing and the adventure/encounters almost feel like they are writing themselves. I created my first one-shot by using these roll tables and some advice from the book and my players had a blast!
This is a great resource and is easy to use. It isn't solely roll tables although those are many and vast. It also includes the basics you need to know about how to create an adventure including different types, varying the play to include all the pillars, motivations for your players to get involved etc. I'll be recommending this to anyone who runs the game!
