Finished layout and rules. Everything in order?

In the future, I highly recommend organizing all the separate files into their own folder. The rar just spewed random pages all over my downloads folder.

In general:
Grammar rules say you should spell out small numbers in text. However, in the context of game rules it makes sense to not be overly strict here. Still, there are a few instances where you might want to revert to spelling, such as, "You cannot perform 2 Attack Actions in the same turn."

In American English, periods and commas go inside quote marks. In the UK it's different. Where is your audience?

You use quote marks quite a bit, and most of the time they seem to break up the text, degrading readability. When referencing cards, you could be referring to them as proper names (use caps) or titles (use italics). You could make an argument for either, I suppose. But be consistent.

Page 1:
No cap after semicolon.

Looks like there's a double space before "30 minutes"

Looks like different font weights on the two titles.

Page 3:
Create the Wound Deck
Consider a chart for the number of card types with the number of players. It could be easier to parse, but this is a minor issue.

Page 4:
"Once last round is played among these players..."

Use of all caps for emphasis is discouraged in formal writing. You could argue that that particular section is informal, but there are other spots in the following pages as well.

Page 5:
etc, should be etc.,
I kinda prefer the omission of the period in this case for readability, but it's technically incorrect. *Shrug*

Inconsistent title spacing.

Why is "Discard" in quotes?

Numbered lists: Periods or parenthesis. Not both.

Page 6:
"If you do not want to or cannot use you Attack Action..."

Using underlined text in the middle of a sentence is a typographic no-no. Use bold or italics. Furthermore, I'm not sure emphasis is really needed here in the first place.

Page 7:

In this case, the diagram lines could stand to be a little bolder, or perhaps colored.

Target
This explanation is a little confusing. How does the targeting reticule show who or what can be targeted?

Range
I think the use of quotes here is superfluous.
The use of "their square" is ambiguous. A more explicit reference to the same square would be clearer.

Card Effect
"The tells any other effects or limitations card has."

In general, the layout needs a little work. Particularly, the distinction between main and sub-categories. The main categories should be consistent in style, and Stat Row breaks this.
The sub-categories would be better if they were indented or smaller to differentiate them.

It would also be helpful to show all the possible symbols, instead of just describing some, such as Burst.

Page 8:
In some cases, the bold text isn't standing out clearly. I think this is mainly do to the the use of a serif font with a strong background.
This page is a great example of that. For example, Target step and Damage step are blending into the paragraph. A little more spacing would help here, or perhaps using a heavier font weight, such as black.

I'm also noticing some inconsistency with the proper names of game items.
Sometimes they are capitalized, sometimes they are just bold, sometimes both. Pick one.

Defending
Again, careful with the underlining.

"Range, shown by the Bow icon, determines the distance your target can be."
I understand the instruction, but I think this is bad grammar. But this isn't my strong suit, so I'll let someone else comment.

Example
"Clint plays Crippling Shot on Donovan, dealing 3 Wounds."
The card shows two wounds?

Why is there an Ironburst Mace card visible?

Why can't he play Move or Double actions next turn? I don't think this has been explained yet.

Page 9:
Ditch the quote marks.

It could be more clear that Valentina is getting a wound both from the card icon and the text effect. Partly because the explanation is light, but also it might not be clear that's (presumably) the edge of the board.

Where are these Shields Damaris is discarding? Is this treasure?

Use of all caps for emphasis.

Page 10:

Consider using a bit more space between the definitions. (You've got plenty of room on the next page.)

Enhance
Missing quote mark.

Half
Use of underlining for emphasis

Unpreventable Damage
As a gameplay note, how does one reduce unpreventable damage? Is that not prevention? Can one unpreventable damage be reduced by one?

Wound
Awkward wording.
Also, why is the underlined section part of this definition? Seems like it should be its own section.

Page 13
Warrior
Damage is caped here, but nowhere else.

Ranger
Armor is caped here, but nowhere else.

Ranger / Wizard
Ampersands should not to be used in place of the word "and"

I agree the background might be a bit much with the text. Maybe try just lightening it a bit to up the contrast.

I think your headers might look better without underline.

I'm going to get very nitpicky with the grammar, hope you don't mind!

Pick a Class
Who picks the starting player? Is it a group thing?

Select your Artifact
You should change "gets first pick of the Artifacts" to "picks an artifact". Otherwise when you say each player does the same you're saying that each player gets first pick, which isn't true.

Create your Deck
Good use of bold here.

Create the Trap Deck
I'd probably move the line about suggestions to another section about alternative versions. For someone's first playthrough it's best to keep it simple.

Placement
I'd change first sentence to something like: "Starting with the first player, and going in clockwise order, each player places their character token on the board."

Small thing but I'd change the quote at the bottom to "Prepare to curse your friends' sudden but inevitable betrayal!" as the betrayal hasn't happened yet. I also don't think it needs commas.

Wounds
Second sentence should be "You get a score of -1 for every Wound you have at the end of the game" or "Every Wound card gives you a score of -1 at the end of the game." The way it's worded right now each card would give -1 for every wound card. That means 1 wound card is -1 points, 2 wound cards is -4 points, 3 wound cards is -9 points.

Treasure
Maybe don't state how you get treasure in section. It's referencing parts of the rules I haven't read yet, like wounding other players and drawing from the Wound Deck. You could just say that Treasure slows you down, but it also gives you points, and leave how you get it to the other sections.

End of Game
I think it would be clearer to just say everyone adds +1 for their Treasure and -1 for their wounds, highest score wins.

Would it be possible to have a second check for ties where the player with the fewest Wounds (or most Treasure) wins. So player 1 (2 wounds, 1 treasure) and player 2 (1 wound) are tied in score, but one of them could be the winner. If it's still tied, go into the extra round.

Trap Phase
Change "effect" to "affect". You should mention the die roll before you say that the starting player "play[s] a new trap card". I initially thought the first player got to place the traps as they pleased, then I saw the die roll. It might be obvious from the dice and the board, but from only reading this I'm not sure how the dice determines which squares are affected. I'm guessing it's a D6 and there are six squares and each is numbered?

Action Phase
Are the cards you play Move Actions and Attack Actions? If not, I'd say "You can also play cards from your hand" to highlight that it's an extra thing you do. I'd also change "Cards are played in front of you" to "Cards you play are placed in front of you", to make it more direct.

Discard and Redraw Phase
I'd suggest:

1) Discard you entire hand and draw up to your max hand size
2) Keep 1 card and discard the rest of your hand then draw up to your max hand size

I have to go now but if I'll try to go through the rest of it later.

Draw and Turn Order.
I don't know if this should be here. It seems like the "Draw 6 cards" should be the last thing you say in the paragraph about making your deck. Then the Turn order can be added more organically after you explain how the action works. Which brings us too ...

Winning and Goal
So this heading seems to have come too early. Because you then explain Wounds and Treasure but you don't explain how the action works or what the goal is. Meaning, you explain that a Wound is worth -1 points and a Treasure is worth 1 point, but you don't explain the game play that will result in you receiving these cards. And then you have an End of Game, explaining when the Wound deck runs out ... again, before you've explained how that might happen.

At this point, on my first read through, I'm not even sure who I'm fighting.

I think you are missing a Game Overview, which should come before the Set Up. You need to briefly explain the game mechanics, the risks and rewards, and how you win.

Player Turn
Removal Phase
It seems odd to read this when I'm learning the game, as it's not an action I take on my first turn. I understand why it is here, but it still seems odd.

Trap Phase
This seems odd here also, if it is not an action taken by all players.

Action Phase
"You will have one move action and one attack action." Does this mean I can move one square and attack one player, or is it dependent on my cards? If the latter it should read, "You may play one attack card and one move card." I am making this guess because of the line "Cards you play are placed in front of you."

Why are you explaining other card actions later? It seems like you are trying to get into detail here, but not too much?

The Card Legend.
This should be much earlier in the Rules. I want to know what the cards look like and what everything means on them when I'm picking my deck.

I wouldn't mind an overall view of the board either. Probably after the note about placing the tokens on the board.

And yes, making the BG texture paler will help with the readability of the rules.

Hope this has been helpful.

Hi.

Sure. But I don't even know what a class is, in this game.

Perhaps adding that page note would help.

Yes, but why is it random some times, and not others? I'm all for randomly choosing them, but why does that change with more players?

I just don't know why you are offering a variant to your game, but with no specifics to it? Why tell them that they can vary the game time here in the set up? If I'm reading this to play the game for the first time, I'm not going to be trying to think of variations that I have to make up. But if there was a clear set up "these cards for a 30 minute game, these cards for an hour game" I would know what I can do.

Otherwise, just don't mention it at all.

So it's a 16 card deck? If so, the sentence "players must now create a 12 card deck." is incorrect. "Players choose 12 cards from their class pool" is clearer.

Of course. It just reads odd as a new player learning the game, because it's not part of the players turn, but something that gets done at the start of each 'round'.

So instead, explain the turn, and when you get to the players playing their cards, you insert the actual different types of card, and how they work. Show a Move action or an Attack action on a card.

I am not sure where it is mentioned, because "Draw to your max hand size" on the Player Turn page is the only place I have seen it.

I would suggest saying, "I have more things to talk about here, but I'll do that later." is also breaking the flow of knowledge. It just created more questions in my mind when I read it. Perhaps say something like

"During the Action phase, you play cards from your hand which allow you to move and attack. The specifics of the various actions printed on the cards are explained on the following page."

The second paragraph reads:

Dungeon Brawl is a 3-5 player game in which the players assume the role of one of many adventurers attempting to defeat one another by receiving the least amount of wounds at the end of the game. This game takes 30 mins to 1 hour to play.

That states that the player that receives the least amount of wounds at the end of the game has defeated the other players. You might think it is a clear paragraph that says the players are fighting each other, but it is not.

It really doesn't. It talks of attacking and defending and targets and wounds. It also talks of Clint and Donovan, but it does not mention that you are attacking "other players".

You're Welcome.
