Its fine but basically a good/high quality, with art and all, 5e homebrew with some baffling layout choices (Ability Score Modifers belong in the character creation book guys). Its very basic, good, but basic and I'd say a better gateway to the OSR. I'd skip this and grab Five Torches Deep Instead, though since it feel more like B/X meets 5e in a more concise and modular way.
