It was a fun read, a couple of gripes:

• The weapon types aren't clear: IE, would a pistol-sized carbine be treated as a rifle or a pistol? What about a pistol-sized shotgun? Or the t-shirt cannon?
• Some of the weapons do have their type listed, so this is frustrating. It's not a big deal, unless you're playing 5E, or you're playing 6E and have a specialization
• Quite a few typos

Other than that, it was enjoyable. 15k words for a $10 price point seems a little pricey, especially when they're releasing 100k word books at $20, but it was worth it.
