Thanks for taking the time to submit! I think it's a good addition to the bundle, and I like the tone and expansive gm tools, but there are some issues.
First, the most significant one is that the terminology for fatigue points is highly inconsistent and effectively contradictory. Gaining a fatigue point should not be the same thing as expending one (especially since regaining one appears opposite to both), unless I am completely lost on how the fatigue system is supposed to work that seems to be the case. There are many other terms that are used in regards to fatigue at various points such as used, and I would suggest you clean up the language a bit and get rid of some of them.
The rest don't really matter by comparison but they are worth noting.
In general some of the language in the rules is misleading. "Every 1 minuteunconscious, they expend 1 FatiguePoint to keep going. If they don'thave any more left, they die." Can be read as as soon as the have no more left rather than if they have no more left when it comes time for them to expend another. I believe the latter is meant based on first aid. The ward spell says to ignore the number rolled for certain numbers, but reduce damage by the roll of a 1d6, which is contradictory. I did not go over all the rules in details so there are likely more things like this.
I'm not sure having 2/3 of all checks made without cost or a relevant skill fail, and only around 1/2 of checks with those factors succeed (if my math is right) is really feasible in an investigative game.
Finally the identity of the game seems a bit inconsistent, combat is supposed to be rare yet I don't see any mention of how damage or involuntary fatigue cost otherwise occurs and there is an extensive list of monsters, magic is supposed to be wild dangerous and unpredictable, yet the spells have set costs, mostly information or slight influence focused outcomes, and the major risks are largely only present if you choose to over fatigue yourself, all of which come down to forgetting something without much overt variety. Also, I can't point to anything specific, but despite the smart phones it really doesn't feel like a game with a modern setting.
