My First Read feedback is at an even lower level. I believe Nitpicking is the term

The Adv/Disadv mechanic is cute - avoids a lot of fuss.
I don't like the d20 resolution - too random.
Biggest Dislike: "fire" a bow? You don't Fire a bow, you loose an arrow, or shoot a bow.

Oh, and there's a typo on page 7, last line of stealth, left out "it".
Good point: I've realised that when I played D&D in the past I must never have actually read the rules, the DM had them and just handed us our sheets. No wonder we got nowhere - we were all accustomed to gritty realism games.
POSITIVE FEEDBACK
Overview on the Rules so far:
D&D is a complex boardgame, a step up from playing Monopoly, a way to introduce children to more advanced games.
Or a way to get a bunch of friends/ family around a table for the simple fun of rolling dice and shouting.
Family or Beer & Pretzels Fun. A Game.
