Why is this position +1 for white

Note to white's 13th move. Perhaps someone who's head isn't hurting as much as mine can help me take a look.

The full game for those very few people who cared:

hi

Thanks.

I actually witnessed the queen blunder o_O

anyway on move 13 I think black's queenside is very vulnerable with those pawns mostly undefended

in my view it seems like both your knights could be in nice outpost squares(I think thats what it's called) with a few good pawn moves

I think this is it, except I'm at a loss as to how white will attack these pawns.

Queenside weaknesses + eventual kingside attack ideas maybe?

true

i feel as if black's overextended but that's just my guess. Maybe white can lock the center and start a kingside attack or something

I mean, does white's position really look like he is organizing a kingside attack tho

cuz white is good at finding good positions

Kinda, looks like a King's Indian attack imo

dunno thinking of g4 and Nf4 ideas, as well as maybe sacrifices on g5 and white can get most, if not all their pieces to the kingside. probably wrong though.

except the f pawn is blocked and black owns more kingside space 

 blacks pieces are dead and he is pushing pawns like a mad man 

If exd5 black could play Nxd5

white's pieces just look better placed than blacks

I like Ne1 here for some reason

Why? It just locks in the knight and disgragrds the kingside attack.
