Only just completed the intro for r.3.0.0. As such, it is just nitpicks concerning dialogue.
#1: Text can be slightly cut off. My monitor is at 1920 x 1080 resolution. An example of text cut-off is during the intro, during the sentence "Are you really so pathetic that you need to be harrasin..." About 1/4th of the "g" is missing at the window edge.
#2: The following text is technically correct, but feels a bit like a run-on sentence. "Because I do whatever the hell I want and and right now I feel like kicking your asses." I suggest shortening it to "Because I do whatever the hell I want, right now I feel like kicking your asses."
#3: Concerning the description of Vengeful Strike, "Causes extra damage equals to damage taken.", should have "equals" be "equal". The plurality of "equal" is dependent on context.
#4: "Ownn, how sweet..." This one is a bit iffy for me. My first guess is that it was meant to be "Oh, how sweet", but the situation implies that Emily is slurring her words from pain. Something like "Ow...that is sweet, but I don't really need it.", might be more clear.
#5: "Ohh, I know that!" Technically, "Ohh" should be "Oh". That said, drawing out some words by adding extra letters is fine for getting a character's energy across. Alter or keep at your discretion - it is more about authorial intent, than anything else.
#6: "Cute? haha..." Should have the "haha" as "Haha". Question marks are generally treated like periods for ending sentences. So it should look like "Cute? Haha..." Should the laugh be a sound effect in text form, I recommend this format: "Cute? *haha*, That's not a word I would use..."
By doing that, you can make it more clear that the sound effect is separate from speech.
#7: "Anyway...Are you heading home, or something?" When periods are used as ellipses, the rule for capitalizing the start of a sentence is disregarded. It should be "Anyway...are you heading home, or something?"
#8: "Yeah...But", should be "Yeah...but"
#9: "Ohh...You know" should be "Ohh...you know"
#10: "Not any place, but as the queen's personal guard." Slightly off, usually it would be written as "Not just any place,". Some places like the United Kingdom would also capitalize "Queen", since that is considered to be a formal title of respect for the ruler. It depends on who is the doing the speaking, as an American usually won't give a capitalization to England's queen.
#11: "C'mon, let's get going then before it gets dark," Technically works, but usually it would be spoken without "then", for a more natural feel.
